ON THE RELAXATION OF THE TRANSLATIONAL ENERGY IN BINARY-MIXTURES OF DENSE HARD-SPHERE SYSTEMS

Recently derived analytical equations for the relaxation time characte ristic for the equilibration of translational energies in binary mixtu res of dense gases possessing different masses and temperatures are ve rified by molecular dynamics simulations. Such comparisons for transla tional collision numbers describing the average number of collisions o f one particle during the relaxation time are also presented. Even for a large ratio of masses fairly good agreement between the theoretical results and those from molecular dynamics simulations is obtained.
