The Nusselt theory for laminar film condensation or evaporation is shown to significantly underpredict existing experimental data because of the presence of waves on the liquid-vapor interface. A heat transfer model is presented which incorporates the results of a previously developed hydrodynamic wavy-film model (Part I). Results based on the model for both local and mean Nusselt numbers are shown to be consistent with available experimental data, and to satisfactorily account for the deviation of the data from the classical Nusselt theory.
