Abstract:Surface tension is a basic thermophysical property which influences the heat transfer and fluid bubbles attached to the surface. Surface tension data for HFCs and HCFCs, which are considered as refrigerant alternatives, is necessary for proper design of air conditioners and refrigeration equipment. The presently available experimental data was used to develop correlations for the surface tension of HFCs and HCFCs. The correlations are compared with correlations in the literature. These correlations accurately represent the experimental data over a wide temperature range with accuracy that can satisfy the requirements of engineering applications.
Keywords:HFC  HCFC  surface tension  alternatives  refrigerants
