Bubble-point pressures and liquid densities of R32, R125 and R134a mixtures.

Author(s) : FUJIMINE T., WIDIATMO J. V., SATO H., WATANABE K.

Summary

The experimental apparatus used is a magnetic densimeter coupled with a variable volume cell. Based on the measured bubble-point pressures, the optimization of the binary interaction parameter of the Peng-Robinson equation, which reproduces the available data within plus or less 1 percent in pressure, has been discussed. Empirical correlations to represent the saturated-liquid and compressed-liquid densities within plus or less 0.4% have also been developed.
