Abstract:

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.

Key words: Surface tension, Corresponding state, Refrigerant, Mixture
