Sinopsis

While the intended teaching style relies heavily on the use of MATLAB, the presentation is very different from texts which prepare elaborate M-files and even menu-driven interfaces. One of the reasons why MATLAB is such a great tool is that it does not have a steep learning curve. Students can quickly experiment on their own. Spoon-feeding with our misguided intention would only destroy the incentive to explore and learn on one's own. To counter this pitfall, strong emphasis is placed on what one can accomplish easily with only a few MATLAB statements. MATLAB is introduced as walkthrough tutorials that encourage students to enter commands on their own. As strong advocates of active learning, we do not duplicate MATLAB results. Students, again, are encouraged to execute the commands themselves. In case help is needed, our Web Support, however, has the complete set of MATLAB results and plots. This organization provides a more coherent discourse on how one can make use of different features of MATLAB, not to mention saving significant printing costs. Finally, we can revise the tutorials easily to keep up with the continual upgrade of MATLAB. At this writing, the tutorials are based on MATLAB version 5.3, and the object-oriented functions in the Control Toolbox version 4.2. Simulink version 3.0 is also utilized, but its scope is limited to simulating more complex control systems. As a first course text, the development of models is limited to stirred-tanks, stirred tank heater, and a few other examples that are used extensively and repeatedly throughout the chapters. Our philosophy is one step back in time. The focus is the theory and the building of a foundation that may help to solve other problems. The design is also to be able to launch into the topic of tuning controllers before students may lose interest. The coverage of Laplace transform is not entirely a concession to remedial mathematics. The examples are tuned to illustrate immediately how pole positions may relate to time domain response. Furthermore, students tend to be confused by the many different design methods. As much as I can, especially in the controller design chapters, the same examples are used throughout. The goal is to help a student understand how the same problem can be solved by different techniques.
 

We have given up the pretense that we can cover controller design and still have time to do all the plots manually. We rely on MATLAB to construct the plots. For example, we take a unique approach to root locus plots. We do not ignore it like some texts do, but we also do not go into the hand sketching details. The same can be said with frequency response analysis. On the whole, we use root locus and Bode plots as computational and pedagogical tools in ways that can help to understand the choice of different controller designs. Exercises that may help such thinking are in the MATLAB tutorials and homework problems.
 

Finally, I have to thank Costas Pozikidris and Florence Padgett for encouragement and support on this project, Raymond de Callafon for revising the chapters on state space models, and Allan Cruz for proofreading. Last but not least, Henry Lim combed through the manuscript and made numerous insightful comments. His wisdom is sprinkled throughout the text.

Download PDF Numerical Techniques for Chemical and Biological Engineers Using MATLAB A Simple Bifurcation Approach by Said Elnashaie

Sinopsis

Mathematical modeling is the science or art of transforming any macro-scale or microscale problem to mathematical equations. Mathematical modeling of chemical and biological systems and processes is based on chemistry, biochemistry, microbiology, mass diffusion, heat transfer, chemical, biochemical and biomedical catalytic or biocatalytic reactions, as well as noncatalytic reactions, material and energy balances, etc. As soon as the chemical and biological processes are turned into equations, these equations must be solved efficiently in order to have practical value. Equations are usually solved numerically with the help of computers and suitable software.
 

Almost all problems faced by chemical and biological engineers are nonlinear. Most if not all of the models have no known closed form solutions. Thus the model equations generally require numerical techniques to solve them. One central task of chemical/ biological engineers is to identify the chemical/biological processes that take place within the boundaries of a system and to put them intelligently into the form of equations by utilizing justifiable assumptions and physico-chemical and biological laws. The best and most modern classification of different processes is through system theory. The models can be formed of steady-state design equations used in the design (mainly sizing and optimization), or unsteady-state (dynamic) equations used in start-up, shutdown, and the design of control systems. Dynamic equations are also useful to investigate the bifurcation and stability characteristics of the processes.
 

The complexity of the mathematical model depends upon the degree of accuracy required and on the complexity of the interaction between the different processes taking place within the boundaries of the system and on the interaction between the system and its surrounding. It is an important art for chemical/biological engineers to reach an optimal degree of sophistication (complexity) for the system model. By “optimal degree of sophistication” we mean finding a model for the process, which is as simple as possible without sacrificing the required accuracy as dictated by the specific practical application of the model. After the chemical/biological engineer has developed a suitable mathematical model with an optimal degree of “sophistication” for the process, he/she is then faced with the problem of solving its equations numerically. This is where stable and efficient numerical methods become essential. The classification of numerical solution techniques lends itself excellently to the system theory classification as well. A large number of chemical/biological processes will be presented, modeled, and efficient numerical techniques will be developed and programmed using MATLAB R 2. This is a sophisticated numerical software package. MATLAB is powerful numerically through its built-in functions and it allows us to easily develop and evaluate complicated numerical codes that fulfill very specialized tasks. Our solution techniques will be developed and discussed from both the chemical/biological point of view and the numerical point of view.

Download PDF METAL CASTING Appropriate technology in the small foundry by STEVE HURST

Sinopsis

The handbook is written for the artisan, metal caster or entrepreneur with more ingenuity than capital. It is aimed at small industries with limited resources. An engineer in a university, or a metallurgist in a large steel works, could pick out many processes that are not described in detail. There is not the space to cover the most recent developments, or processes demanding high capital outiay, important though these developments are. Where appropriate these processes are mentioned in outline. Simple guidelines in the first section are followed by examples. Using the examples and Contents list, you should have no difficulty finding the process suited to the object you wish to manufacture. For quick reference there is a Glossary covering the different processes and materials in alphabetical order.

Finally, only a fool insists that there is one way, and one way only, to approach a practical problem. There are many useful methods; the difficulty lies in selecting the method most appropriate to the job, bearing in mind the financial and supply problems of the workshop.

Download PDF CHEMICAL ENGINEERING A NEW PERSPECTIVE by Kohei Ogawa

Sinopsis

There is no clear scope to improve the methods of investigation of the phenomena that are expressed by formulae such as those in Newtonian mechanics. On the other hand, no two phenomena that can be expressed by probability terms are similar and as such, the methods used to investigate such phenomenon (e.g., the evaluation indices for mixing and separation operations/equipment) differ based on the nature of the phenomenon or process. In other words, there is no consistent technique for treating such phenomena that should be expressed by probability terms. The author has considered that such phenomena should be treated from a consistent viewpoint and reached to put on the glasses of information entropy to treat the phenomena. In this chapter, before discussing the main subject, the steps in the development of chemical engineering are surveyed; further, the necessity of a consistent viewpoint in chemical engineering is clarified. Next, the concept of information entropy and its important features are explained in detail. In addition, the sensitiveness of human experience for quantity is discussed in order to examine the suitability of the introduction of information entropy. It is believed that by at least comparing the expression for the amount of human feeling with that for information entropy, the suitability of the introduction of information entropy will be understood by those readers who have a strong intention to develop new fields in chemical engineering and new approaches for studying chemical engineering.

Download PDF Chemical Engineering: Visions of the World by R.C Darton

Sinopsis

This essay set outs some speculations about the changing role of Chemical Engineering in the 21st century. To this end, I first look back well beyond my own undergraduate experiences of Chemical Engineering at Sydney University in the 1950’s to the earlier shape and traditions of the subject. I then sketch a personal vision of how ever-accelerating advances in our understanding of the molecular machinery of life, and the consequent biotechnological applications, are likely to affect us, bringing both new benefits and new problems. Chemical Engineering, defined more broadly than most current practitioners can imagine and shading into biomedicine, will be at the heart of delivering the benefits, and caught up in most of the problems. Specifically, I will touch on: implications for curricula, and the linked question of attracting adequate numbers of able students; patterns of partnership between academia and industry; questions of intellectual property, and what should and should not be patentable. I will conclude with thoughts about the interplay between science/ engineering and society.

Download PDF Nanotechnology Safety by Ramazan Asmatulu

Sinopsis

Nanotechnology is the creation, processing, characterization, and application of materials at nanoscale (in the range of one-billionth of a meter). It can also be related to the systems or processes that provide goods and/or services at this scale . According to K. E. Drexler, “nanotechnology is the principle of manipulation of the structure of matter at the molecular level. It entails the ability to build molecular systems with atom-by-atom precision, yielding a variety of nanomachines” . These materials commonly referred to as nanomaterials exhibit unusual and exotic properties that are not present in the traditional bulk materials of the same kinds.

Nanoscience is the study of the fundamental principles of molecules and structures with at least one dimension between 1 and 100 nm. These structures are known as nanostructures. Nanotechnology is the application of these nanostructures into useful nanoscale materials and devices . When the materials are in the nanoscale level, they usually exhibit superior properties. For example, copper becomes transparent at the nanoscale; inert materials, such as platinum and gold, become active; and melting temperatures of the nanomaterials can be drastically reduced. Nanotechnology has the potential to change our standard of living . Some nanomaterials applications include energy storage and production, information technology, medical technology, manufacturing, food and water purification, instrumentation, and environment. Nanotechnology-based products (currently more than 1,350 available on the market) include electronic components, nanopaints, storage devices, stain-free fabrics, cosmetics, and medical components . shows the nanofiber fabrication process and a scanning electron microscopy (SME) image of the resultant nanofibers.

Download PDF Extractive Metallurgy of Copper FOURTH EDITION by W.G Daveport

Sinopsis

Copper is most commonly present in the earth’s crust as copper-iron-sulfide and copper sulfide minerals, e.g. chalcopyrite (CuFeS2), bornite (CusFeS4) and chalcocite (Cu2S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu (open pit mines) to 1 or 2% Cu (underground mines). Pure copper metal is produced from these ores by concentration, smelting and refining, Fig. 1.1.

Copper also occurs in oxidized minerals (carbonates, oxides, hydroxy-silicates, sulfates), but to a lesser extent. Copper metal is usually produced from these minerals by hydrometallurgical methods, Fig. 1.2. Hydrometallurgy is also used to produce copper metal from chalcocite, Cu2S.

A third major source of copper is scrap copper and copper alloys. Production of copper from recycled used objccts is 10 or 15% of mine production. In addition, there is considerable re-meltinghe-refining of scrap generated during fabrication and manufacture.

This chapter introduces the principal processes by which copper is extracted from ore and scrap. It also indicates the relative industrial importance of each.

Download PDF OXFORD PAPERBACK REFERENCE: A Dictionary of Chemical Engineering by Carl Schaschke

Sinopsis

The purpose of this dictionary is to provide a quick, useful, and comprehensive reference to commonly used and, in some case, less commonly used terms from the field of chemical engineering. As with any dictionary, it is intended to provide definitions to words; it is not merely a brief glossary of terms, nor is it intended to be encyclopedic, with lengthy and overly long explanations. It is aimed at students at school and undergraduate students who will encounter, perhaps for the first time, unfamiliar technical terms. It is also aimed at postgraduates engaged in chemical engineering research as well as practitioners of chemical engineering in industry who may require clarification regarding terms. This dictionary is also aimed at the general reader who in the course of their work or daily lives may encounter unfamiliar terms. The focus of the dictionary is scientific and engineering terms. It includes core and fundamental terms commonly encountered across all degree programmes of chemical engineering worldwide. It includes many scientific and engineering concepts, laws, theories, and hypotheses. It includes significant organizations, international legislation, and biographical notes of influential scientists and engineers who have contributed to the development of the discipline. There are definitions of many types of specialist process equipment encountered in chemical engineering. This dictionary should therefore enable the reader to distinguish between a lute and a dead leg or a Hortonsphere and a holley-mott. Being a diverse discipline, there is an emphasis on established processes across a wide range of industries spanning nuclear, mineral, oil and gas, food, and pharmaceutical processing. Some older or former processes are also included where their usage was pioneering at the time or influenced later processes. Products, raw materials, and feedstocks are included, though to a far lesser extent; only those upon which major industries are based, such as crude oil, natural gas, minerals, and ores, are included. The full details of chemicals and their properties are included in the sister dictionaries such as the Oxford Dictionary of Chemistry .

As a branch of engineering in its own right, the roots of chemical engineering extend back to the nineteenth century. While many of the original and familiar terms are still in use today (such as unit operations attributed to Arthur D. Little), chemical engineering in the twenty-first century has expanded considerably and diversified into many new technological fields such as renewable energies, nanotechnology, and biomolecular engineering. Many students and professional engineers alike encounter new terms almost daily with which they may not be familiar or entirely clear. This dictionary therefore aims to provide up-to-date, clear, concise terms and definitions, and other useful and valuable information that can be used as a quick reference source.

The dictionary features over 3,000 of the most commonly encountered terms, although the number actually used by chemical engineers is far greater! There are many cases where words are used uniquely within a particular industry, or within a single industrial organization, and are not be found anywhere else. These have not been included. In providing a definition of each of the included words, the aim has been to be inclusive of all aspects of chemical engineering without being too general. If one starts with the very name chemical engineering , there are no doubt as many definitions as chemical engineers! Founding member of the Institution of Chemical Engineers Norman Swindin once described chemical engineering as engineering without wheels . An amusing definition but it falls a long way short of being helpful or informative.

The SI system of units has been used throughout although it is recognized that British Imperial and American customary units are still widely used in many industries. Reference has been made to commonly encountered units and conversions presented where appropriate.

Download PDF How to Design and Build Centrifugal Fans for the Home Shop by David J. Gingery

Sinopsis

Nearly everyone is familiar with "squirrel cage" fans found in home heating, air conditioning and ventilating systems. The squirrel cage is just one of many forms of centrifugal fans and blowers designed in a wide range of sizes for many different applications. Smaller fans appear on the market from time to time as surplus or salvage, some of which may find practical use in home shop applications. It certainly makes little sense to construct a fan for a special purpose if one is readily available at low cost. But some applications require air at high pressure and volume, and the fans and blowers usually available as surplus will probably not meet the requirements. At this point it becomes practical to design and build a fan for the job at hand.

It is not difficult to design a fan for a specific purpose when the importance of the effect of various factors is understood. Although state-of-the-art fan design has become highly technical, mainly due to advances in jet propulsion and turbine technology, you can easily design a fan to suit your specific needs. The basic principles that are discussed in this manual have remained unchanged for more than 150 years. Surprisingly, common materials and ordinary tools are adequate for construction of fans capable of delivering air at high volume and moderately high pressure. Because there are many design parameters that can be manipulated, fans can be designed to meet nearly any requirement of volume, velocity and pressure.

The most common application for a high pressure and/or high volume fan is in forcing air into a furnace or in exhausting dust and fumes. A blacksmith's forge or a melting furnace are examples of forced draft. The exhaustion of welding fumes or the collection of dust from woodworking machines or grinders can be easily accomplished in the small shop at low cost. These are areas of safety, protection and convenience that are usually neglected because a new fan capable of doing this work is too expensive. Because such a fan is seldom found used or surplus, it is worthwhile to consider building one.

This manual will show you how to determine the diameter and width of a fan wheel and at what speed to run it to achieve the desired pressure and volume. Several methods for building the wheel are discussed. The layout procedure for the scroll housing has been simplified. From the formula given for calculating the amount of power required to run a fan you will learn (perhaps to your amazement) how much work can be done by a common fractional horsepower motor. You will be shown how to build simple balancing equipment and how to use it. You will also learn how to test the performance of experimental fans with an easily built manometer and pitot tube. Only a few easily understood and applied formulae are needed to guide you. You will enjoy building several projects that will upgrade your shop and make your work environment safer and more comfortable. As in any shop activity there are dangers that may not be readily apparent. You should be aware that centrifugal force and generated air pressure puts great strain upon the fan wheel and other parts of the blower. Foreign material in the air stream or loose pieces breaking off the wheel can reach velocities of up to several thousand feet per minute. Very serious injury or possibly even death can result if persons are struck. Take all practical steps to protect yourself and others. Electrical wiring must be properly installed to avoid shock and fire hazards. Always be very safety conscious in the shop, and provide protection promptly whenever danger appears.

Download PDF Integrated Product and Process Design and Development : The Product Realization Process Second Edition by Edward B. Magrab

Sinopsis

The process of creating and making artifacts has been around since the beginning of humankind. It was first applied to the creation of implements for survival: weapons, shelters, clothing, and farming. These implements were improved upon with the appearance of such inventions as fire, the wheel, and steel, and as time went on they became more substantial and more sophisticated. As societies evolved, so did their needs and the artifacts that were required to satisfy those needs. In addition, many societies evolved from being local societies to being regional ones, simultaneously transforming their local economies into regional ones. In the beginning, these transformations took hundreds to thousands of years. Since the start of the industrial revolution about 300 years ago, the pace of development and improvement of devices and artifacts has increased dramatically. During this period of time we have seen companies grow from local entities to global entities, and we have seen in the industrialized nations the economies transition for national economies to interdependent global economies. This has been particularly true in the last half of the twentieth century.

This transformation from primarily local societies to ones that must now compete globally has had a very substantial influence on the product realization process. It is an environment in which one must compete on cost, quality, performance, and time-to-market on a worldwide basis. This requires individuals and companies to reexamine how they go about creating products and services and how these products and services can be brought to the marketplace. During the last 30 years it has become clear that the way to do this is through an integrated approach to the product realization process. This approach tends to do the following: “flatten” organizational structures; involve many more constituencies in the process at the very beginning; place greater emphasis on the customer, product quality, cost, and time-to-market; use a large amount

The book has been divided into separate chapters covering variousbranches of the study. So far as possible, it has been arranged so that it can be worked through progressively from the beginning to the end although certain self-contained chapters may be read separately. Ideas are developed assuming a minimum knowledge, and every attempt has been made to present the work so that it does not appear simply as a collection of facts. It is hoped that in this way it has been made more interesting and readable.

There are numerous worked the text. Where possible the examples are taken from past examination papers of various examining institutions. These past examination questions have been used in order that the student will appreciate the standard required at the earliest opportunity. The author has made a step-by-step solution of the worked examples, thus piloting the student through the work without making undue assumptions. It must be remembered that whereas many steps may appear obvious to some, and could therefore be left out of the text, these same steps are not so clear to others. It is hoped that the book will cater for all.
