Engineering Thermofluids

Thermofluids, while a relatively modern term, is applied to the well-established field of thermal sciences, which is comprised of various intertwined disciplines. Thus mass, momentum, and heat transfer constitute the fundamentals of th- mofluids. This book discusses thermofluids in the context of thermodynamics, single- and two-phase flow, as well as heat transfer associated with single- and two-phase flows. Traditionally, the field of thermal sciences is taught in univer- ties by requiring students to study engineering thermodynamics, fluid mechanics, and heat transfer, in that order. In graduate school, these topics are discussed at more advanced levels. In recent years, however, there have been attempts to in- grate these topics through a unified approach. This approach makes sense as thermal design of widely varied systems ranging from hair dryers to semicond- tor chips to jet engines to nuclear power plants is based on the conservation eq- tions of mass, momentum, angular momentum, energy, and the second law of thermodynamics. While integrating these topics has recently gained popularity, it is hardly a new approach. For example, Bird, Stewart, and Lightfoot in Transport Phenomena, Rohsenow and Choi in Heat, Mass, and Momentum Transfer, El- Wakil, in Nuclear Heat Transport, and Todreas and Kazimi in Nuclear Systems have pursued a similar approach. These books, however, have been designed for advanced graduate level courses. More recently, undergraduate books using an - tegral approach are appearing.

Thermofluids: From Nature to Engineering presents the fundamentals of thermofluids in an accessible and student-friendly way. Author David Ting applies his 23 years of teaching to this practical reference which works to clarify phenomena, concepts and processes via nature-inspired examples, giving the readers a well-rounded understanding of the topic. It introduces the fundamentals of thermodynamics, heat transfer and fluid mechanics which underpin most engineering systems, providing the reader with a solid basis to transfer and apply to other engineering disciplines. With a strong focus on ecology and sustainability, this book will benefit students in various engineering disciplines including thermal energy, mechanical and chemical, and will also appeal to those coming to the topic from another discipline. Presents abstract and complex concepts in a tangible, accessible way Promotes the future of thermofluid systems with a focus on sustainability Guides the reader through the fundamentals of thermofluids which is essential for further study.

This text is concerned with the methods in which different types of energy are converted from one form to another. In particular, the book examines why so many of the energy conversion processes which involve heat have a low efficiency rating.

A fully comprehensive guide to thermal systems design covering fluid dynamics, thermodynamics, heat transfer and thermodynamic power cycles Bridging the gap between the fundamental concepts of fluid mechanics, heat transfer and thermodynamics, and the practical design of thermo-fluids components and systems, this textbook focuses on the design of internal fluid flow systems, coiled heat exchangers and performance analysis of power plant systems. The topics are arranged so that each builds upon the previous chapter to convey to the reader that topics are not stand-alone items during the design process, and that they all must come together to produce a successful design. Because the complete design or modification of modern equipment and systems requires knowledge of current industry practices, the authors highlight the use of manufacturer’s catalogs to select equipment, and practical examples are included throughout to give readers an exhaustive illustration of the fundamental aspects of the design process. Key Features: Demonstrates how industrial equipment and systems are designed, covering the underlying theory and practical application of thermo-fluid system design Practical rules-of-thumb are included in the text as ‘Practical Notes’ to underline their importance in current practice and provide additional information Includes an instructor’s manual hosted on the book’s companion website

This innovative book uses unifying themes so that the boundaries between thermodynamics, heat transfer, and fluid mechanics become transparent. It begins with an introduction to the numerous engineering applications that may require the integration of principles and tools from these disciplines. The authors then present an in-depth examination of the three disciplines, providing readers with the necessary background to solve various engineering problems. The remaining chapters delve into the topics in more detail and rigor. Numerous practical engineering applications are mentioned throughout to illustrate where and when certain equations, concepts, and topics are needed. A comprehensive introduction to thermodynamics, fluid mechanics, and heat transfer, this title: Develops governing equations and approaches in sufficient detail, showing how the equations are based on fundamental conservation laws and other basic concepts. Explains the physics of processes and phenomena with language and examples that have been seen and used in everyday life. Integrates the presentation of the three subjects with common notation, examples, and problems. Demonstrates how to solve any problem in a systematic, logical manner. Presents material appropriate for an introductory level course on thermodynamics, heat transfer, and fluid mechanics.

Combining previously unconnected computational methods, this monograph discusses the latest basic schemes and algorithms for the solution of fluid, heat and mass transfer problems coupled with electrodynamics. It presents the necessary mathematical background of computational thermo-fluid dynamics, the numerical implementation and the application to real-world problems. Particular emphasis is placed throughout on the use of electromagnetic fields to control the heat, mass and fluid flows in melts and on phase change phenomena during the solidification of pure materials and binary alloys. However, the book provides much more than formalisms and algorithms; it also stresses the importance of good, feasible and workable models to understand complex systems, and develops these in detail. Bringing computational fluid dynamics, thermodynamics and electrodynamics together, this is a useful source for materials scientists, PhD students, solid state physicists, process engineers and mechanical engineers, as well as lecturers in mechanical engineering.

Thermofluid Modeling for Sustainable Energy Applications provides a collection of the most recent, cutting-edge developments in the application of fluid mechanics modeling to energy systems and energy efficient technology.

This textbook provides a concise and clear incremental evolution of the introductory fluid mechanics and thermodynamics knowledge for first and second year engineering undergraduates. If you are a first or second year student of mechanical, chemical, aeronautical, marine or civil engineering this book is for you. Also this book is a suitable (and cheap) text for other science degrees where core knowledge of fluid mechanics and thermodynamics is required, for instance environmental science and meteorology. It may also help you if you are taking courses online. It is designed to support the lectures and examples you are given and help you answer the questions you are going to try to solve. It does not skip much, but there is not much padding. It does not seek to emulate the standard texts from the major publishers, which include lots of colour, examples, usually a vast array of web resources, DVDs and so on. I take the view that the lecturers who deliver your undergraduate course know their stuff and provide you with lecture slides which they explain, examples and other questions for you to try yourself. The book delivers the material incrementally, in more-or-less the order the students are actually taught the material over years 1 and 2. The challenge of developing a new introductory 'thermofluids' course, and the dearth of well priced and appropriate textbooks on the subject inspired me to write my own. I also saw no reason to give the rights to a publisher when none of the material is new and self-publishing is so straightforward. Taking this route allows me to keep the cost down to a small fraction of the combined cost of the alternatives.
