Various truncations for the virial series of a binary fluid mixture of additive hard spheres are used to analyze the location of the critical consolute point of this system for different size asymmetries. The effect of uncertainties in the values of the eighth virial coefficients on the resulting critical constants is assessed. It is also shown that a replacement of the exact virial coefficients in lieu of the corresponding coefficients in the virial expansion of the analytical Boublík–Mansoori–Carnahan–Starling–Leland equation of state, which still leads to an analytical equation of state, may lead to a critical consolute point in the system.

AbstractThe specific heat of liquid metals is calculated using a fluid of Percus-Yevick plus tail as a reference system together with the Cumming potential in a random-phase approximation. It is shown that the improved semi-empirical hard sphere direct correlation function proposed by Colot et al. leads to a drastic improvement of Cp values over the HS model
