Show affiliationsTwo different levels of the free-volume approximation for the calculation of the phase diagram of a asymmetric hard-sphere mixture are compared to direct simulations of the phase behaviour. The mean-field-level free-volume approach, where only the statistically pre-averaged free volume is accounted for, is already in satisfactory agreement with the simulation results. Taking correlations into account within the free-volume approach improves the agreement with the solid branch of the phase diagram but, remarkably, this version performs somewhat worse for the fluid branch.
