The First Edition of Thermal Systems Design: A Most Practical Guidebook was published to help students visualize the landscape of a thermal system design project and to equip their intellectual “toolkits” with a wide variety of techniques for applying solid engineering theory toward a useful and successful design, while exposing them to predictable stumbling blocks that will require ingenuity to overcome. The intended audience is mechanical or chemical engineering students seeking a capstone design course for thermal-fluid systems, including heating, drying, boiling, refrigeration, air conditioning, compression, expansion, combustion, and power generation. Practitioners of thermal engineering design may also find this to be a helpful reference work – one that offers breadth, clarity, and simplicity.
