In this work, a new method based on the modified Enskog theory (MET) is presented for calculation of transport properties at high densities ρ > ρc). The main limitation of using the MET is lack of experimental data for co-volume, b0. We have substituted b0 from hard sphere (HS) theory nd zero density transport properties from the kinetic theory of gases for HS in the MET expression, because of ...

Results are presented of a systematic study of the transport properties of the rough hard sphere fluid. The rough hard sphere fluid is a simple model consisting of spherical particles that exchange linear and angular momenta, and energy upon collision. This allows a study of the sole effect of particle rotation upon fluid properties. Molecular dynamics simulations have been used to conduct exte...

The Navier-Stokes transport coefficients of a granular gas are obtained from the Chapman-Enskog solution to the Boltzmann equation. The granular gas is heated by the action of an external driving force (thermostat) which does work to compensate for the collisional loss of energy. Two types of thermostats are considered: (a) a deterministic force proportional to the particle velocity (Gaussian t...

Polynomial expansions are of widespread use in a gas kinetic theory. For linearized Boltzmann equation, such an expansion is a basis of the wide-known Enskog-Chapman method [1], [2]. For the nonlinear case, this method was developed in Burnett's [3] and Grad's [4] works. As it was proved by Kumar [5], the best time-consuming expansion is that over so called spherical Hermite polynomials. Along ...
