Abstract
The one-dimensional unsteady flow field induced by a planar incident shock wave propagating into a gas-particle mixture without chemical reactions has been calculated using the PLM-algorithm based on the high-resolution Riemann solver and the MacCormack scheme. The effects of Mach number (M s = 2.0 – 5.15), inital loading ratio (η = 0.1 – 4.0) and particle diameter (D p = 10 – 100 μm) on the flow field behind the incident shock wave are investigated. The numerical results of the traces of the incident and reflected shock wave and the accelerated planar interface of the gas-particle mixture are in good agreement with the experimental data. It is also shown that the gasdynamic behaviour in the gas-particle mixture behind an incident shock wave of moderate strength is remarkably different from that behind a weak one due to the existence of a bow shock in front of each particle.
