A two component model of the linearized Boltzmann equation in a half-space incorporating three degrees of freedom is studied. The linearized collision term is taken to be a summation over a suitable combination of the collision invariants. Preliminary results concerning exponents of compensating factors involved in the Wiener-Hopf factorization of the dispersion matrix are presented. Comparison is...
The problem of the steady emission of a monatomic gas from a plane boundary into a half-space under finite pressure is considered. The use of a trimodal approximating distribution function and moments derived from the nonlinear Boltzmann equation leads to a four-moment system that can be solved exactly. The solution is naturally arrived at in two steps: First, an algebraic connection problem between...
