✦ Synopsis

Molecular dynamics simulations on Lennard-Jones mixture in the supercritical region are performed. The number of the molecules in the unit cell is 23328 and the mole fraction is 0.5. The concentration fluctuations near the critical point are large compared to the ideal mixing. The mutual diffusion coefficient normalized by the self-diffusion coefficient has a small value nearthe critical density because of the lar e concentration fluctuation. The heat capacity, partial molar volume an t9 correlation lengths of density and concentration in the supercritical region are compared with those at the normal density.

We test a proposed relation between mutual diffusion coefficient and viscosity in suspensions which is essentially identical to a dynamic mode-coupling theory of diffusion in binary fluid mixtures near a critical mixing point. In contrast to conventional treatments of suspension hydrodynamics, this
