The reliability of the people giving you the facts is as important as the facts themselves.
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, convective heat transfer involves the combined processes of unknown conduction and advection.
Heat transfer to or from a fluid flowing through a tube R. Shankar Subramanian A common situation encountered by the chemical engineer is heat transfer to fluid flowing through a tube. This can occur in heat exchangers, boilers, condensers, evaporators, and a host of other process equipment.emember that the purpose of using a heat transfer coefficient is to calculate the heat flux between the wall and the fluid. In the case of uniform wall flux, we can use an energy balance directly to infer the way in which the bulk average temperature of the fluid changes with distance along the axial direction.
