Résumé

This paper presents a literature survey of the available data of the experimental surface tension data for refrigerants. The experimental data were collected for the following pure fluids: R11, R12, R13, R13B1, R14, R21, R22, R23, R32, R113, R114, R115, R123, R123a, R124, R125, R134, R134a, R141b, R143a, R152a, R218, R225ca, R225cb, R227ea, R236ea, R236fa, R245ca, R245fa, R365mfc, R846, and R1234yf. Experimental data were regressed with the most reliable semi-empirical correlating methods based on the corresponding state theory existing in the literature. To minimize the deviation between the predicted data and the experimental data and to find the optimal equation for data representation, a design of experiment procedure coupled with the Yates algorithm and the steepest ascent method was adopted. Finally, the influence of the dipole moment on the refrigerant surface tension prediction was discussed and a new equation to represent the surface tension of refrigerants was presented.
