双组分混合物在花瓣形翅片管上的冷凝传热

CONDENSATION HEAT TRANSFER OF BINARY MIXTURE ON PETAL-SHAPED FIN TUBE

对双组分混合物在一种新型强化传热管———花瓣形翅片管上的冷凝进行了实验研究和机理分析．实验结果表明，双组分混合物在水平花瓣形翅片管上强制对流冷凝时的传热膜系数是光滑管的５～６倍．

Condensation of binary mixture on a new type of heat transfer enhancement tube, the Petal_Shaped Fin Tube, is studied experimentally and analyzed mechanically in this paper. It is proved by experimental results that the forced convective condensation heat transfer coefficients of binary mixture on the horizontal Petal_Shaped Fin Tube are 5 to 6 times those of the smooth tube.
