【Abstract】 The effects of thermal radiation on conjugate film condensation on one side of a vertical wall and natural convection on the other are investigated. By employing the conjugate condition, ordinary differential equations for wall temperature distribution and film thickness have been obtained. The wall temperature, film thickness, velocity and temperature profiles in the condensation film and the convection boundary layer as well as the wall temperature gradient are calculated for a wide range of parameters.更多还原
