ABSTRACT
There are many engineering applications such as electronic equipment, small (milli-, micro-, or nano-) scale channels, and compact heat exchangers that required laminar flow heat transfer analysis and design. This chapter focuses on how to solve fully developed heat transfer problems for flow between two parallel plates or inside circular tubes. Both uniform and asymmetric thermal boundary conditions are considered. Given the thermal boundary conditions, readers can analytically determine the velocity profile, the friction factor, the temperature profile, and the Nusselt number for these cases. In addition, methods to analytically predict heat transfer in both developing flow and thermal entrance regions, with various thermal boundary conditions, are provided. A sample of flow in rectangular channels with various aspect ratios and thermal boundary conditions is also presented.
