Abstract
This introductory chapter develops the concept of a thermal circuit and analytical and numerical methods used to analyze simple circuits. Subsequent chapters will apply and build on them using heat transfer examples from common experience. Key elements, namely, resistors, capacitors, batteries, and current sources, are introduced. Resistive/capacitive (RC) network diagrams are used as modeling tools to visualize the flow of heat, an abstract massless quantity. Hence, the term “thermal circuit.” The focus of this book is to develop heat transfer modeling as a design tool, rather than as a pure science. The principles apply to other areas in engineering (and life) practice. Specific tools are developed in this textbook that pertain to heat transfer phenomena, most of which can be captured in thermal circuits.
