WebUniversity of Notre Dame 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.
