When heat transfer is the heat transfer between the surface of a solid body and a moving fluid or gas , respectively.

Heat transfers are described mathematically by the heat transfer coefficient and the dimensionless Nusselt number .

The heat transfer separates the heat transfer taking place at the interface from the convection , i.e. the transfer associated with the flow movements of the fluid, and from the heat conduction in the two media. If necessary, thermal radiation can also be of importance in the heat transfer .
