摘要：

Accurate correlations are given for the temperature dependence of the surface tension of 37 fluids included in NIST's REFPROP program. The surface tension of these fluids was not included in the most recent version of this program, V9.12. A set of data was constructed for each of these fluids by including principally the values given in the DIPPR, DETHERM, and TDE databases and Wohlfarth and Wohlfarth's book. For some fluids, other available sources of data were added in order to obtain adequate sets. The correlation expression used is the same as used for other fluids in REFPROP. For 31 fluids it was enough to use two adjustable coefficients, whereas four coefficients were needed for the other 6 fluids. For 19 fluids, the mean average percentage deviation was below 1%, and for another 16 it ranged from 1% to 2%. (C) 2014 AIP Publishing LLC.
