摘要 The surface tensions of 21 pure refrigerants have been predicted by a new improved equation based on the principle of corresponding states with double referenced fluids.The average absolute deviation between the calculated surface tensions from the equation and the experimental result is-0.015 mN/m.The surface tensions of 9 binary mixtures were calculated in consideration of certain mixing rules.And the average absolute deviation between the calculated surface tensions from the equation and the experimental result is-0.251 mN/m.The new improved prediction equation can be used for calculating the surface tension of environmental friendly refrigerants.
