Pressure consistency for binary hard-sphere mixtures from an integral equation approach

Abstract

The site-site Ornstein-Zernike equation combined with the Verlet-modified bridge function has been applied to the binary hard sphere mixtures and pressure consistency has been tested. An equation of state has been computed for the case where a packing fraction is $\eta =0.49$, diameter ratios are ${\sigma }_2/{\sigma }_1=0.3$ and $0.6$, and the mole fractions are $x_1=0.125,0.5,0.75$, and $1$. An excess chemical potential for each component has been obtained as well. Our findings for thermodynamic properties are in good agreement with available data in literature.
