摘要
分析了液膜内动力和换热特性，提出了一种环状流下的两相强制对流蒸发的６层速度分布模型，并利用比拟理论进行了分析和计算，预测其换热系数．通过与实验数据对比，结果表明预测值与实验数据有较好的一致性．
An analytical model is proposed for developed annular flow,which is based on a six layer velocity distribution supposition and analogy between momentum and heat transfer.The calculated values of heat transfer coefficients are then compared with experiment data.The results show that they coincide well with each other.
