NEW SURFACE TENSION EQUATION FOR REFRIGERANTS
This work presents an analysis of the available data of the experimental surface tension data for refrigerants. The experimental data were collected after a careful literature survey for the following pure fluids: R11, R12, R13, R13B1, R14, R21, R22, R23, R32, R113, R114, R115, R123, R124, R125, R134, R134a, R141b, R143a, R152a, R218, R227ea, R236ea, R236fa, R245ca, R245fa, R365mfc and R1234yf. Experimental data were regressed with the most reliable semi-empirical correlating methods based on the corresponding state theory existing in the literature: the Brock, Bird and Miller equation (Brock and Bird, 1955; Miller, 1963), the Pitzer equation (Pitzer, 1995), the Sastri and Rao equation (Sastri and Rao, 1995), the Schmidt et al. equation (Schmidt et al., 1996), and the Miqueu et al. equation (Miqueu et al., 2000). To minimize the deviation between the predicted data and the experimental data and to find the optimal equation for experimental data regression, a (μ+λ)-Evolution strategy is adopted. After a careful statistical analysis of the results based on the Evolution Strategy (ES), a new formula based on the golden ratio with improved representation of the experimental results was found and here proposed.
