WebHeat transfer is by conduction. The heat flux q y in the y -direction is related to the temperature gradient by Fourier’s law. (12) qy = −k∂T ∂y q y = − k ∂ T ∂ y. where k denotes the thermal conductivity, with heat considered to be transferred predominantly by free electrons in the case of sufficiently pure metals [ 2, 6 ].
