摘　　要：一种新的用于推算ＣＦＣｓ替代物表面张力的基因贡献法刘志刚，杜素芬，阴建民，赵小明（西安交通大学能源与动力工程学院西安７１００４９）关键词表面张力，氟里昂，氯氟烃替代物，推算法１引言ＣＦＣｓ物质由于其对大气臭氧层的破坏作用而将被禁用。在ＣＦＣｓ替代物的...A new group-contribution estimation method is developed for determining the surface tension of Freon of methane and ethane systems based on the Van der Waals correlation and great data analyses. The new method is verified by calculating the surface tensions of 16 kinds of Freon and the calculating deviation is generally within ±5%. The surface tensions of HCFC-133a are estimated with the present method and by comparing the results with experimental values the deviations are within 12%. The estimated values are provided for the designs of synthetic process of HFC-134a and equipments as well as other applications for engineering calculation.
