Laminar film condensation of a liquid metal in a vertical channel in the presence of an electromagnetic force

An implicit finite-difference method is used to solve the boundary layer form of the conservation equations for both a laminar liquid phase and a turbulent vapor phase for the problem of liquid metal condensation on a vertical channel in the presence of an electromagnetic force. A special coordinate system, which adjusts its cross stream width to conform with the boundary layer, was used. The velocity and temperature profiles for the two-phase condensation problem are obtained by the numerical technique for different values of the applied electric and magnetic fields, the entrance interface velocity and the entrance liquid layer thickness. The condensation heat transfer was investigated and is discussed. The use of an electromagnetic force accelerated the liquid film and improved the condensation heat transfer for the case of a liquid metal
