When a shock wave propagates over many small solid particles on a horizontal wall, some particles near the surface of the layer are lifted and dispersed into the shockinduced flow. These dispersed particles is called the dust cloud. This phenomenon is actually seen in galleries of coal mines or in pipelines for neumatic transportation of powder, and mixing dispersed flammable dust particles with high-temprature and high-pressure gas behind the shock wave sometimes causes the dust explosion. And this phenomenon includes some interesting factors, such as the shock structures interacted with the dust layer, interactions between gas and solid particle, and interactions between solid particles.
