摘　　要：基于电场增强蒸发薄液膜的传热性能，本文将电场力对液膜的作用形式转化为气液界面间的压差，并据此针对正辛烷在施加电场的硅质管道中的流动特性和传热特性建立电场强化薄液膜区换热的数学模型。该模型结合薄液膜所受毛细力、范德华力以及电场力，运用数值计算分析方法得出电场强化薄液膜区域换热的结论。结果表明，电场能延长蒸发薄液膜区域，极大增强蒸发薄液膜的传热能力。Based on the electric field enhance the thin liquid film evaporation heat transfer performance.This paper forms the function of the electric field force of liquid membrane into a pressure differential between the gas-liquid interface.According to the flow characteristics and heat transfer characteristics of the octane in the siliceous pipe which applies an electric field,building a mathematical model of the heat transfer in the thin liquid film zone applying an electric field.This model combined with the thin liquid film by capillary forces, van der Waals forces and electric field forces.Using numerical analysis method of the electric field to strengthen the conclusion of thin liquid film zone heat. The results show that the electric field can extend the thin liquid film evaporation area and greatly enhance the thin liquid film evaporation heat transfer ability.
