<b>Thermal Systems Design</b> <p><b>Discover a project-based approach to thermal systems design</b> <p>In the newly revised Second Edition of <i>Thermal Systems Design: Fundamentals and Projects, </i>accomplished engineer and educator Dr. Richard J. Martin offers senior undergraduate and graduate students an insightful exposure to real-world design projects. The author delivers a brief review of the laws of thermodynamics, fluid mechanics, heat transfer, and combustion before moving on to a more expansive discussion of how to apply these fundamentals to design common thermal systems like boilers, combustion turbines, heat pumps, and refrigeration systems. <p>The book includes design prompts for 14 real-world projects, teaching students and readers how to approach tasks like preparing Process Flow Diagrams and computing the thermodynamic details necessary to describe the states designated therein. Readers will learn to size pipes, ducts, and major equipment and to prepare Piping and Instrumentation Diagrams that contain the instruments, valves, and control loops needed for automatic functioning of the system. <p>The Second Edition offers an updated look at the pedagogy of conservation equations, new examples of fuel-rich combustion, and a new summary of techniques to mitigate against thermal expansion and shock. Readers will also enjoy: <ul><li>Thorough introductions to thermodynamics, fluid mechanics, and heat transfer, including topics like the thermodynamics of state, flow in porous media, and radiant exchange</li> <li>A broad exploration of combustion fundamentals, including pollutant formation and control, combustion safety, and simple tools for computing thermochemical equilibrium when product gases contain carbon monoxide and hydrogen</li> <li>Practical discussions of process flow diagrams, including intelligent CAD, equipment, process lines, valves and instruments, and non-engineering items</li> <li>In-depth examinations of advanced thermodynamics, including customized functions to compute thermodynamic properties of air, combustion products, water/steam, and ammonia right in the user’s Excel workbook</li></ul> <p>Perfect for students and instructors in capstone design courses,<i> Thermal Systems Design: Fundamentals and Projects</i> is also a must-read resource for mechanical and chemical engineering practitioners who are seeking to extend their engineering know-how to a wide range of unfamiliar thermal systems.
