聚四氟乙烯表面滴状冷凝传热的理论模型与计算

Theoretical Study of Dropwise Condensation Heat Transfer on the Surface of Polytetrafluoroethylene

摘要: 对滴状冷凝传热机理进行了简述,建立了聚四氟乙烯冷凝壁面的滴状冷凝传热模型,用该模型进行的理论计算显示,脱落直径的大小和过冷度的不同对冷凝表面的热通量有一定的影响。

Abstract: Dropwise condensation mechanism was described.The heat transfer model was set up on the basis of PTFE condenser wall.Theoretical calculation with the model indicates that the heat flux was affected by drop size and surface subcooling.
