Ps. Fialho et Can. Decastro, PREDICTION OF LIQUID DENSITIES FOR HALOCARBON MIXTURES BY A MODIFIED HARD SPHERE-DE SANTIS EQUATION OF STATE, Fluid phase equilibria, 118(1), 1996, pp. 115-119
In a companion paper, we dealt with the problem of predicting the liqu
id behaviour of pure refrigerants. It is the purpose of the present pa
per to extend the use of the Hard Sphere De Santis (HSDS) model by ass
ociating it with mixing and combination rules to predict the liquid st
ate densities for mixtures of halocarbon refrigerants. The deviations
obtained between the experimental data, available for binary and terna
ry mixtures, and the HSDS model have shown an uncertainty of 1.5% for
T less than or equal to 0.9. This was the uncertainty claimed for the
model, when applied to pure fluids.
