The structure of a shock wave close to a wall
Abstract
The large gradients observed in wall shocks in shock tube experiments make the wall region of interest for studying effects associated with large deviations from local thermal equilibrium. Density measurements and numerical simulation show that the gradients in the flow variables are much larger at the wall than in the flow away from it. This applies also to relaxation effects. In the present paper, Bird's (1976) direct Monte Carlo simulation technique is applied to the determination of the distribution function of molecular velocities with a view toward obtaining a gaskinetic description of flow region at the wall.
