Convective heat transfer , often referred to simply as convection , is the transfer of heat from one place to another by the movement of fluids . Convection is usually the dominant form of heat transfer in liquids and gases. Although often discussed as a distinct method of heat transfer, ...
In addition, the temperature drop could be obtained by analyzing the pressure data combined with the thermodynamic model including the convective heat transfer empirical formulae. Compared the analyzed temperature drop with that obtained by using the "stop method", it can be found that the ...
