Effect of the temperature potential across the condensate layer in a forced convection three-dimensional boundary-layer flow

An analysis is made for laminar film condensation on a rotating flat plate situated in a large body of pure saturated vapor. The problem is formulated as an exact solution of the boundary-layer and energy equations. Numerical solutions are obtained for different Prandtl numbers and different temperature potentials. Results are given for the heat transfer, as well as the condensate layer thickness and temperature and velocity profiles. It is found that in all the cases investigated, the temperature profile is essentially linear. Also the effect of increasing the temperature potential across the liquid film tends to increase the mass transfer in the x and z directions, the film thickness, the interfacial shear and the skin friction, while it decreases the Nusselt number and thus causes a reduction in the heat transfer
