Abstract

The Widom test particle method was used to estimate the overlap volume for hard disks under shear flow. The volume of free space which can house an additional particle without overlap with other particles will differ from its equilibrium value because of the distortion of the solvation shell of every particle under the impact of shearing motion. In this way the overlap volume unambiguously characterizes the structure of nonequilibrium systems. The probability of finding voids with necessary sizes decreases with the shear rate as one might expect. Owing to the technical limitation inherent in the method the economically attainable shear rates and densities produced only small effects. Under certain reasonable assumptions the calculated nonequilibrium overlap volumes can be related to a nonequilibrium generalization of the chemical potential. We discuss this possibility.
