Convective heat transfer is the transfer of energy between a surface and a fluid moving over the surface and is primarily used as a boundary condition when solving solid/fluid heat transfer problems (for example, quenching, electronic device cooling, heat exchangers, and so on). It is governed by Newton’s law of cooling.
