A general attenuation law of moderate planar shock waves propagating into dusty gases with relatively high loading ratios of solid particles

The governing equations describing the propagation of a moderate planar normal shock wave into a homogeneous dust-gas suspension were formulated and solved numerically using the flux-corrected transport (FCT) technique. The numerically predicted attenuation of the shock wave was compared with the experimental results of Sommerfeld. Good agreement was obtained. It was found that the attenuation of moderate normal planar shock waves propagating into dusty gases with relatively high loading ratios of solid particles can be described by a general attenuation law.
