Description
Description
Thermal System Design and Simulation covers the fundamental analyses of thermal energy systems that enable users to effectively formulate their own simulation and optimal design procedures. This reference provides step-by-step guidance on how to mathematically formulate objective functions and design constraints and develop strategies to solve them to obtain optimal solutions with minimal computational effort. The book uniquely illustrates the methodology of combining information flow diagrams to simplify system simulation procedures needed in optimal design. Expanded and updated for currency, Thermal System Design and Simulation includes case studies and a comprehensive presentation on the dynamics of thermal systems and control systems needed to ensure safe operation at varying loads. Designed to give readers the hands-on skills needed to develop their own customized software for simulating and designing thermal systems, this book is useful for anyone interested in obtaining advanced knowledge of thermal system analysis and design.
