Five methods of heat transfer

Example of situation with conduction, convection, and radiation

WebConvection. The transfer of heat energy between a surface and a moving fluid at different temperatures is known as convection. It is actually a combination of the mechanisms of diffusion and the bulk motion of molecules. Near the surface where the fluid velocity is low, diffusion (or random molecular motion) dominates. WebHeat energy can flow by conduction, convection or radiation. It always flows from a region of high temperature to a region of low temperature i.e. from hot to cold. Conduction
