竖壁下降液膜发展段中的流动和换热分析

AnalysisofLaminarFlowand Heat Transfer of Falling Liquid Film Along a Vertical Plate in the Developing Region

该文采用边界层相似解对竖壁下降液膜发展段中的层流流动与换热特性进行了分析，获得了定壁温时速度边界层和温度边界层发展段长度及换热系数的计算表达式．

The characteristics of laminar flow and heat transfer of falling liquid film along a vertical plate in the developing region are analyzed by using the boundary layer similarity solution. The relationship between the developing length of hydrodynamic and thermal boudary layer and heat transfer coefficient for constant surface temperature are obtained.
