Strong shock wave propagation in a mixture of a gas and dusty particles in a moving medium
Abstract
The effects of strong shock wave propagation in a moving medium are discussed in relation to the perturbation theory. Numerical solutions are derived for the velocity, density, pressure, and temperature distributions under various conditions. Only the onedimensional flow problem is considered as a routine extension to the similar problem of two or threedimensional cases, and the shock speed produced when a certain amount of energy is suddenly released is calculated. Physical quantities in the flow field behind the strong shock front are also measured. Results indicate that the effects of the moving medium depend significantly on the mass concentration of the solid particles and the ratio of the specific heats of the gas; and the moving stream is observed to increase the velocity of the flow behind the strong shock, and decrease its density and pressure in the flow field.
