Predicting Random Close Packing of Binary Hard-Disk Mixtures

This paper introduces a novel method for predicting the random close packing (RCP) fraction in binary hard-disk mixtures. The significance lies in its simplicity, accuracy, and universality. By leveraging a parameter derived from the third virial coefficient, the model provides a more consistent and accurate prediction compared to existing models. The ability to extend the method to polydisperse mixtures further enhances its practical value and broadens its applicability to various hard-disk systems.
