Abstract
The dynamics of mixing and entrainment induced by a steady turbulent boundary layer flow over a loose dust bed is studied with our second-order Godunov code. The problem considered models the late-time flow of explosions over soil surfaces, and extends previous shock-tube studies that focused on the early-time lofting of dust behind the shock front. As in our previous work, an equilibrium model was used for the dust-air mixture. The calculated boundary layer growth and mean-flow profiles are in reasonable agreement with wind-tunnel measurements. This suggests that our Convective Mixing Model is capable of simulating a wide variety of turbulent dusty flows.
