Forced Convection
KEY CONCEPTS
The term forced convection is used if fluid motion and mixing is caused by a fan or pump.
The transfer of heat from the surface of a heat exchanger to the fluid being pumped through it is an example of forced convection.
5.1 CONVECTIVE HEAT TRANSFER
Most industrial applications such as heat transfer in heat exchangers, boilers, quenching of metals, and IC engines involve heat transfer between a solid surface and a fluid. Convective heat transfer due to temperature difference between a surface and fluid is influenced by the fluid properties, the geometry of the surface, and the fluid velocity. The convection heat transfer is determined using the Newton's law of cooling.
