Laminar film condensation on a finite-size horizontal plate with suction at the wall
1992
Abstract The problem of two-dimensional, steady-state film condensation on a finite-size, isothermal, horizontal plate with suction at the wall is examined theoretically for the case in which a cold plate faces upward. The dimensionless film thickness profile along the plate is found to be a function of the parameter Ja/Pr (Jacob number over Prandtl number) and the suction parameter Sw. An essential part of the present analysis is the use of the concept or condition that the boundary layer depth at the plate edge is equal to a critical (minimum) depth. The dimensionless heat transfer coefficients are also found to be functions of parameters Ja/Pr, Ra/Ja, and Sw. Furthermore, the dimensionless heat transfer coefficients increase as suction parameters Sw increase.
