A problem of considerable practical interest is the film condensation on a horizontal finite-size plate. In the design of evaporative condensers, distillation processes and other industrial applications, the heat transfer due to condensation on bodies with horizontal surfaces is an important consideration. Here, a theoretical analysis of two-dimensional, steady laminar film condensation on a finite-size horizontal wavy plate is studied for the case in which a cold plate faces upwards. The present study considers that the wavy characteristic length, amplitude and the depth of boundary layer at the plate edge is equal to a minimum depth. The dimensionless heat transfer coefficients and the dimensionless film thickness along the surface are found to be functions of five parameters: dimensionless wave length and amplitude, Pr, Ja and Ra.
