Numerical study of the three-dimensional laminar film condensation

An analysis is performed to study the effects of the body force on the heat transfer characteristics of laminar filmwise condensation over a rotating flat plate, maintained at a uniform temperature. The study is based on the use of the constant-property boundary-layer equations. The governing equations describing the boundary layer are transformed to non-dimensional forms and then solved by two-point implicit finite-difference methods. Numerical results for the velocity and temperature distributions, the local mass transfer in both the streamwise and crosswise directions, the local Nusselt number and the local skin friction are represented for different values of Prandt 1 numbers with different values of the body force. Generally, it is found that the local mass transfer in the crosswise directions, the crosswise velocity and the local Nusselt number increase with an increase in the body force. In addition, an increase in the body force results in control of the liquid-layer thickness and thus an improvement in the condensation heat transfer
