| 摘 要： | 研究了混合气体在垂直圆管内的对流凝结传热。利用修正的膜模型与Nusselt凝结理论建立了换热数学模型，预测了壁面温度对膜厚度和界面温度的影响，计算了凝结液膜厚度，并与报相热阻法进行比较，研究结果表明该模型更接近实验果，提出了混合气体对流凝结换热与Nusselt凝结的不同。

| Abstract: | This paper discusses the convective condensation of mixture gas in a vertical A mathematical model was set up by combining modified film model and Nusselt's condensation theory. The effect of wall temperature on film thickness and interfacial temperature was predicted and film thickness was calculated. Comparing with gas phase thermal resistance method, the film model is in better agreement. The difference between convective condensation Nusselt's condensation was illustrated. |
