This paper concerns an analytical study of laminar film condensation on horizontal isothermal surfaces. The flow that arises on a surface of finite length is studied to determine the temperature field and the local heat transfer to the surface. The study considers both transient and steady laminar flow. The governing nonlinear equations are also considered for the circumstance when the surface tension effects are included. The profiles in the condensate film, for steady laminar flow, are found to be strongly dependent on the edge conditions and on the length of the horizontal condensing surface. The dependence on vapor properties and on the surface temperature is also determined. The surface tension effects are found to be negligible, even for quite small values of the Bond number, for a surface terminated by a round fall. The results for transient, laminar, flow show that the transient effects are large for highly viscous condensing fluids and for low gravity fields. An expression for the local Nusselt number is also obtained. |
