Low density equation of state of asymmetric hard sphere mixtures

The equation of state of highly asymmetric hard sphere mixtures at low and moderate densities is investigated using NpT Monte Carlo simulations. The discrepancies of the estimated fifth virial coefficient with the reported values of Saija et al. (Saija, F., Fiumara, G. and Giaquinta, P. V., 1996, Molec. Phys., 89, 1181) led us to compute such a coefficient. The new results are fully compatible with the compressibility factors estimated by Monte Carlo simulation and show excellent agreement with the predicted coefficients from the Boublik and Mansoori et al. equation of state.
