从理论上对下降液膜在自由表面上存在反向剪切力和蒸发散热情况下的换热特性进行了分析 ,得到了膜厚 ,换热系数的无量纲关系式 ,讨论了剪切力、液膜雷诺数、壁面热流、蒸发率对流动和传热的影响。
The heat transfer characteristics of the descending liquid film on the free surface under the condition of reverse shear force and evaporative heat dissipation were theoretically analyzed. The dimensionless relationship of film thickness and heat transfer coefficient was obtained. The relationship between shear force, Effect of Liquid Film Reynolds Number, Wall Heat Flow and Evaporation Rate on Flow and Heat Transfer.
