Why is it windy at the seaside?. Cold air sinks. Where is the freezer compartment put in a fridge?. Freezer compartment. It is put at the top, because cool air sinks, so it cools the food on the way down.. presence of bulk fluid motion and by conduction in the absence of it. Therefore,. conduction in a fluid can be viewed as the limiting case of convection, corresponding to the case of quiescent fluid (Fig. 6–1).. Nimesh Gajjar. CONVECTIVE HEAT TRANSFER. . Convection heat transfer involves . fluid motion . heat conduction. The fluid motion enhances the heat transfer, since it brings hotter and cooler chunks of fluid into contact, initiating higher rates of conduction at a greater number of sites in fluid. Therefore, the rate of heat transfer through a fluid is much higher by convection than it is by conduction. In fact, the higher the fluid velocity, the higher the rate of heat transfer..
