含不凝气体的蒸气冷凝换热的计算方法

On the calculation of condensation heat transfer in the presence of noncondensing gas

建立了用换热参数计算合不凝气体的蒸气冷凝有效换热温差的方法，推导了换热参数的表达式，讨论了组元扩散流对传热的影响。

Using the heat transfer parameter,an analysis type for the effective temperature difference ofcondensation heat transfer in the presence of noncondensing gas is set up.An universal formaul.a of the heattransfer parameter is proposed,and the influence of species diffusion on condensation is discussed.
