摘　　要：用分段步进迭代解法对水蒸汽在不凝性气体存在的情况下在竖管内强制对流凝结时局部的热、质传递进行了分析研究。计算结果与实验数据吻合较好。A stepwise iterative solution method has been applied to study the heat and mass transfer of a vapor in the presence of a non-condensable gas,where the gas mixture is flowing downward inside a vertical tube. The obtained heat and mass transfer results are in good agreement with the experimentally obtained data. The method described in this paper and the corresponding program can be applied to design the condenser and to predict condensation heat transfer data.
