Mathematical and Physical Modeling of Materials Processing Operations


Book Description

The past few decades have brought significant advances in the computational methods and in the experimental techniques used to study transport phenomena in materials processing operations. However, the advances have been made independently and with competition between the two approaches. Mathematical models are easier and less costly to implement, but experiments are essential for verifying theoretical models. In Mathematical and Physical Modeling of Materials Processing Operations, the authors bridge the gap between mathematical modelers and experimentalists. They combine mathematical and physical modeling principles for materials processing operations simulation and use numerous examples to compare theoretical and experimental results. The modeling of transport processes is multi-disciplinary, involving concepts and principles not all of which can be associated with just one field of study. Therefore, the authors have taken care to ensure that the text is self-sustaining through the variety and breadth of topics covered. Beyond the usual topics associated with transport phenomena, the authors also include detailed discussion of numerical methods and implementation of process models, software and hardware selection and application, and representation of auxiliary relationships, including turbulence modeling, chemical kinetics, magnetohydrodynamics, and multi-phase flow. They also provide several correlations for representing the boundary conditions of fluid flow, heat transfer, and mass transfer phenomena. Mathematical and Physical Modeling of Materials Processing Operations is ideal for introducing these tools to materials engineers and researchers. Although the book emphasizes materials, some of the topics will prove interesting and useful to researchers in other fields of chemical and mechanical engineering.




Modeling in Materials Processing


Book Description

Mathematical modeling and computer simulation are useful tools for improving materials processing. While courses in materials processing have covered modeling, they have been devoted to one particular class of materials--polymers, metals, or ceramics. This text offers a new approach, presenting an integrated treatment of metallic and non-metallic materials. The authors show that a common base of knowledge--specifically, the fundamentals of heat transfer and fluid mechanics--unifies these seemingly disparate areas. They emphasize understanding basic physical phenomena and knowing how to include them in a model. The book also includes selected numerical methods, a wealth of practical, realistic examples, and homework exercises.




Modeling Multiphase Materials Processes


Book Description

Modeling Multiphase Materials Processes: Gas-Liquid Systems describes the methodology and application of physical and mathematical modeling to multi-phase flow phenomena in materials processing. The book focuses on systems involving gas-liquid interaction, the most prevalent in current metallurgical processes. The performance characteristics of these processes are largely dependent on transport phenomena. This volume covers the inherent characteristics that complicate the modeling of transport phenomena in such systems, including complex multiphase structure, intense turbulence, opacity of fluid, high temperature, coupled heat and mass transfer, chemical reactions in some cases, and poor wettability of the reactor walls. Also discussed are: solutions based on experimental and numerical modeling of bubbling jet systems, recent advances in the modeling of nanoscale multi-phase phenomena and multiphase flows in micro-scale and nano-scale channels and reactors. Modeling Multiphase Materials Processes: Gas-Liquid Systems will prove a valuable reference for researchers and engineers working in mathematical modeling and materials processing.




Flow Visualization in Materials Processing


Book Description

This book presents a comprehensive review of particle image velocimetry (PIV) and particle tracking velocimetry (PTV) as tools for experimental fluid dynamics (EFD). It shares practical techniques for high-speed photography to accurately analyze multi-phase flows; in particular, it addresses the practical know-how involved in high-speed photography, including e.g. the proper setup for lights and illumination; optical systems to remove perspective distortion; and the density of tracer particles and their fluorescence in the context of PIV and PTV. In this regard, using the correct photographic technique plays a key role in the accurate analysis of the respective flow. Practical applications include bubble and liquid flow dynamics in materials processes agitated by gas injection at high temperatures, mixing phenomena due to jet-induced rotary sloshing, and wettability effects on the efficiency of the processes.




Modeling of Steelmaking Processes


Book Description

From the prediction of complex weather patterns to the design of swimsuits, modeling has, over the years, quietly but steadily become an essential part of almost every field and industry-and steelmaking is no exception. Factors such as visual opacity, high operating temperature, and the relatively large size of industrial reactors often preclude di




The Mathematical and Physical Modeling of Primary Metals Processing Operations


Book Description

A book that provides the mathematical and physical modelling techniques developed for representing metals processing operations such as extraction, refining and solidification. Often referred to as transport phenomena, these techniques are specific to primary metals and used for process optimization and process development now becoming essential as industry moves to on-line computer control of metal processing. This subject matter covers the components of models based on fluid flow; heat and mass transfer; obtaining measurements (data acquisition); optimization of the process; and numerical solutions. Covers the basic principles of numerical solution of differential equations, both finite differences and finite elements. Examples included.

Modelling of Materials Processing


Book Description

This is a book about mathematical modelling. It focuses on the modelling of the preparation of materials. Materials are important, of course, in an economic sense: the "goods" of goods-and-services are made of materials. This provides a strong incentive to produce good materials and to improve existing materials. Mathematical modelling can help in this regard. Without a doubt, modelling a materials processing operation is not strictly necessary. Materials synthesis and fabrication processes certainly existed before the invention of mathematics and computers, and well before the combined use of mathematics and computers. Modelling can, however, be of assistance--if done properly--and if used properly. The mathematical modelling described in this book is, at its root, a rather formal, structured way of thinking about materials synthesis and fabrication processes. It requires looking at a process as a whole. It requires considering everything that is or might be important. It requires translating the details of a given physical process into one or more mathematical equations. It requires knowing how to simplify the equations without over-simplifying them.

Book Description

Mechatronics has emerged as its own discipline over the past decade, yet no reference has lived up to the demands of being a working guide for designing and implementing the new generation of mechatronic systems. Uniting an international team of leading experts, Mechatronic Systems: Devices, Design, Control, Operation and Monitoring rises to the challenge of providing a practical, comprehensive, and detailed guide to the theory and application of modern mechatronics. Weaving the Multi-Domain Tapestry This book treats all components of the mechatronic system as a unified whole, combining mechanics, electronics, intelligent control, sensors, actuators, and communication networks through integrated design. Extensive cross-referencing lends this work a coherence not found in other books on mechatronics, which amount to little more than collections of papers. Real-World Guidance from the Experts Extensive examples and case studies take you effortlessly from theory to analysis, design, and application. Convenient snapshots in the form of tables, graphs, illustrations, and summaries give you immediate access to the information you need. Mechatronic Systems: Devices, Design, Control, Operation and Monitoring is a critical compendium of need-to-know information covering mechatronic devices, communication and control technologies, mechatronic design and optimization, and techniques for monitoring and diagnosis.
