"WebIn case of contact between the boundary of the solid and a ﬂuid at temperature θ, the heat transfer can occur by convection. In this case qnc = hc (T(x,y,z,t)−θ), (1.25) where hc is the convection heat transfer coeﬃcient, measured in W m2·K. A body at temperature T loses heat by radiation if surrounded by a medium at temper-ature θ. " - On the propagation of heat in solid bodies
