摘要：
A model is presented that considers the influence of capillary pressure on the evaporation of a liquid film on a vertical nat plate. The governing equations are derived and numerically integrated with a step-variable Runge-Kutta method. The numerical results are compared with the analytical solution from Nusselt's film condensation theory. The deviation from the Nusselt film theory become very prominent when the liquid film becomes thin enough. This can be attributed to the fact that the Nusselt film theory does not consider the influence of capillary pressure on the shape of the liquid film.
