RAREFIED PLASMA FLOWS.

Abstract

The theory and the numerical analysis are presented which detail a study of the discrete ordinate method as applied to the numerical solution of the nonlinear Boltzmann equation. The first physical problem treated was the spatially homogeneous relaxation of a nonequilibrium distribution function toward equilibrium. This application stresses the role of the complicated nonlinear Boltzmann collision integral and provides a convenient framework in which to study and improve the accuracy and speed of the computations. In the second application, the technique is applied to the study of the one-dimensional shock tube problem. Finally, the application of the discrete ordinate method to the problem of rarefied hypersonic flow about an isolated body is described. (Author)
