Direct statistical simulation of collisional relaxation in mixtures of gases with a large difference in concentrations

New Monte Carlo global weight method for the approximate solution of the nonlinear Boltzmann equation

“…The weight modifications of the method of direct statistical simulation (DSS) for the approximate solution of the nonlinear Boltzmann kinetic equation were constructed earlier [1,8,13,14]. In those works, separate particles were assigned 'weights' associated with the artificial redistribution of the types of particles at the initial instant.…”
