Abstract In order to predict the condensation heat transfer coefficient precisely, this work aimed at proposing a generalized model with a wide scope of parameters applicability, namely, we presented an improved model that can predict the condensation characteristics which based on heat and mass transfer analogy with consideration of gas compressibility factor, fog formation factor, film waviness factor, suction factor and eddy diffusion factor. The improved model is suitable for those conditions: low pressure condensation at plate-shape and curved-shape surface with natural/forced convection, high pressure condensation at curved shape surface with natural convection. The improved model shows good applicability with the scope of the pressure is up to 2 MPa and the non-condensable (NC) gas mass fraction up to 90%. Six experimental databases (including 436 data) were chosen to validate this model. More than 97% of the results predicted by the improved model were within ±30% bands.

基于真实气体状态方程和雾形成的冷凝传热传质改进模型

摘要 为了准确预测冷凝传热系数，本文提出了一种参数适用范围广的广义模型，即提出了一种基于传热传质类比的可预测冷凝特性的改进模型。考虑气体压缩系数、雾形成系数、薄膜波纹系数、吸入系数和涡流扩散系数。改进后的模型适用于自然/强制对流的板状曲面低压凝结，自然对流曲面高压凝结。改进后的模型具有良好的适用性，压力范围可达2 MPa，不凝气质量分数可达90%。选择了六个实验数据库（包括 436 个数据）来验证该模型。改进模型预测的结果中有 97% 以上在 ±30% 范围内。
