Book Description
A study was made of the structure of plane, steady shock waves in a neutral monatomic gas 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 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. (Author).
Shock Wave Structure in a Fully Ionized Gas Based on Multi-component Fluid Theory

Book Description
The multi-component continuous approach for the investigation of the gasdynamics of a plasma is presented. More information about the flow properties of a plasma can be obtained than from the classical magnetohydrodynamic approach. Also, the resulting equations appear to be more easily solved than the Blotzmann equation of classical kinetic theory. The basic macroscopic conservation equations for a non-reacting multi-component plasma are presented. The fluid properties of each component are referred to the mean velocity of that component. Therefore, no limitations are placed on the magnitude of the diffusion velocities. The effects of electric and magnetic fields are included. The equations for a two-component mixture are used to study the structure of a shock wave in a fully-ionized hydrogen gas. It is assumed that the momentum exchange and energy exchange between the ions and electrons are important because of the strong Coulomb forces present. (Author).

Book Description
The structure of a shock wave in a monatomic gas has been the subject of investigation by many authors. In this problem there are two relevant mean free paths, viz., the length over which upstream distribution is altered by collisions and another length over which downstream particle distribution is changed through collisions. Appropriate distribution functions over these length scales are postulated and a moment method to solve the Boltzmann equation is described to solve the shock wave structure problem. For strong shocks the results agree with those of Mott-Smith's theory while for weak shocks, the results are in agreement with Navier-Stokes and other approximate solutions. (Author).

Book Description
Physics of Shock Waves and High-Temperature Hydrodynamic Phenomena, Volume II presents interpretations of the physical basis of shockwaves and high-temperature hydrodynamic phenomena and gives practical guidance to those who work with these subjects in science and modern technology. This volume contains chapters discussing such topics as the shockwave structure in gases; physical and chemical kinetics in hydrodynamic processes; the radiative phenomena in shock waves and in strong explosions in the air; thermal waves and shockwaves in solids; and self-similar processes in gasdynamics. Physicists, engineers, researchers, and professors and students in the field of the physical sciences will find the book very educational.
