The structure of plane, steady shock waves in a neutral monatomic gas was studied using the Boltzmann equation of the kinetic theory of gases and considering the molecules to be rigid elastic spheres. Two collision models are considered: In one model the postulate of a Maxwellian distribution of the lateral components of the molecular velocity is used and the kinetic model of Krook is applied to the resulting collision integral thus reducing the Boltzmann equation to a linear form in the longitudinal velocity distribution function for which the corresponding transport equations are also derived. The second model uses the Boltzmann equation and the associated equations of transfer. As in the original Krook kinetic model, conservation of particle number, momentum, and energy are also ensured at each collision for the present modified kinetic model. A number of parameterized gas models of both types have been constructed, and equations governing these parameters have been obtained by using the method of moments. (A.G.W.)
