Abstract : The Direct Simulation Monte Carlo Method was further developed to deal with molecules having rotational degrees of freedom. Rotational relaxation was studied for both rough sphere and weighted sphere molecules. Shock wave structure in a gas of rough sphere molecules was also investigated. Other applications of the method included: (1) Heat Transfer in the presence of a strong gravitational field. (2) The breakdown of translational equilibrium in an unsteady expansion wave. (3) The structure of a spherically imploding shock wave. (4) The reflection of a shock wave from a diffusely reflecting wall. (5) The use of computer display facilities to illustrate the velocity distribution function within a strong shock wave. (Author)
