Therefore, developing a good understanding of external flow and external forced convection is important in the mechanical and ther-mal design of many engineering systems such as aircraft, automobiles, build-ings, electronic components, and turbine blades. The flow fields and geometries for most external flow problems are too, fluid. Whereas in forced convection, the fluid is forced to flow over a surface or in a tube by external means such as a pump or fan. Mechanism of Forced Convection Convection heat transfer is complicated since it involves fluid motion as well as heat conduction.
