Laminar film condensation on the underside of an inclined flat plate

A semi-infinite inclined plate is immersed in a quiescent pure vapor at the saturation temperature, and a laminar condensation flow near the thermal leading edge is driven by the induced pressure gradient parallel to the plate. The flow is steady and replenishment of the liquid by condensation maintains the liquid-vapor interface at a fixed location. A numerical scheme is employed to solve the condensate and vapor boundary layer equations for steam and water for different angles of inclination. An approximate solution is obtained for large cooling rates and angles in the range 0-90 deg. This solution indicates a simple correlation of the exact numerical results.
