INFINITELY STRONG SHOCK STRUCTURE IN A BINARY GAS MIXTURE,
Abstract
The problem of infinitely strong shock structure in a binary gas mixture is formulated using a bimodel approximation for each gas constituent. The bimodel consists of a delta function for the hypersonic flow upstream and a nonsingular function for the hot flow downstream. The Boltzmann equations are split into four equations. Under the local Maxwellian approximations for the nonsingular functions and an approximations on the force constants in the molecular interaction the problem is reduced to a numerical integration of three moment equations involving three nondimensional parameters, namely, the mass ratio, the number density ratio, and the cut-off parameter ratio. The behavior of the singular points of the system of three moment equations at plus or minus infinity is analyzed, and a numerical integration is proposed. (Author)
