Convection heat transfer is complicated since it involves fluid motion as well as heat conduction The fluid motion enhances heat transfer (the higher the
Convection is the dominant heat transfer mechanism in fluids that are poor thermal conductors such as water and air Convection is the 'pump' that circulates
The flow is initiated by a change in the density of fluids incurred as a result of heating Mixed Convection: combined forced and natural convection Process h
Convective heat transfer occurs when a gas or liquid flows past a solid surface whose temperature is different from that of the fluid
Thus the focal point in convection heat transfer is the determination of the temperature distribution in a moving fluid In
Heat can be transferred in three ways: by conduction, by radiation and by convection In conduction, the molecular energy is directly exchanged, from the hotter
Heat can be transferred in three different modes: conduction, convection, and radiation All modes of heat transfer require the existence of a temperature
Convection heat transfer takes place whenever a fluid is in contact with a solid surface that is at a different temperature than the fluid
