Consider flow in a corner shown below. Creeping flow can be used. However, Vo is not zero at the vapor-liquid interface because there is evaporation Tw >Tsat (Saturation temperature) . Write down the creeping flow Solution, subject to the known boundary Conditions and the one unknown one . Write down the Conductive -convective equation for temperature T. show that latent heat is needed at the vapor-liquid interface for one boundary condition Show that the two systems (flow and temperature) can
