摘要：Evaporation at thin liquid film can significantly enhance heat transfer process. A detailed mathematical model predicting the heat and mass characteristics of the evaporating thin film is developed. The model considers effects of inertial force, evaporation coefficient, interface thermal resistance, and disjoining pressure. It is found that the interface thermal resistance is in inverse proportion to the evaporation coefficient. The heat and mass transport characteristics decreases sharply as the evaporation coefficient decreases. The inertial force tends to enhance the heat and mass transport characteristics of the evaporating thin film. However the Reynolds number of the liquid flow in the evaporating thin film is far lower than unity, and thus the effect of the inertial force can be neglected.
