抄録
内容記述 When a shock wave propagates over a dust layer composed of many small solid particles, the particles are lifted and dispersed, leading to a dust cloud in the shock-induced flow. In the present study, the initial process of forming the dust cloud was numerically simulated to examine its dynamic mechanism. A continuous model was used for the gas phase and a discrete model for the solid particles, where gas-particle and particle-particle interactions were taken into account. The simulated dust cloud was close to experimental results. It was found by comparing several types of dust layers that the upward velocity of lifted particles was more produced by particle-particle interactions than by fluid lift forces such as the Saffman force and the Magnus force. Moreover, it was confirmed that a relatively strong downward flow was induced just behind the foot of the shock by its curved shape, which promotes the interactions and causes an overpressure on the wall.
