Heat transfer in forced convection boiling of oil–non‐azeotropic binary refrigerant mixtures

Abstract:

In this paper, the results of the heat transfer, forced convection, boiling characteristics of non‐azeotropic refrigerant mixtures and oil are presented. This includes heat transfer coefficients for pure and binary mixtures under boiling conditions outside enhanced surface tubing. Local convective heat transfer coefficients have been determined using a modified Wilson‐plot technique. Heat transfer correlations were established as a function of the binary mixture mass flow rate, and oil concentration, as well as key flow parameters. Copyright © 1993 John Wiley & Sons, Ltd.
