Conduction–Convection Heat Transfer

Heat transfer problems are of critical importance in almost all areas of engineering and technology, especially in the field of mechanical engineering. Over several decades, engineers and scientists have been working on solving these problems by designing and optimizing components and systems needed for transferring, handling, and storing thermal energy. Heat can be transferred via different mechanisms, like conduction and convection. Heat conduction is the process of transferring heat from a high temperature region to a low temperature region within a body via molecular motion. Heat convection occurs by macroscopic fluid motion, e.g., when a fluid is flowing along a surface and has a different temperature than the solid surface. In this chapter, some practical nonlinear conduction–convection heat transfer problems will be discussed. Differential or partial differential equations that govern the physical process will be introduced and solved via different analytical approaches.
