Abstract

Expansion waves propagating into particle beds are found in many manmade and natural applications. Rapid decompression of a highly pressurized powder bed or a volcanic eruption are two such examples. In this investigation, we perform fully resolved simulations of expansion waves propagating into particle beds of three different volume fractions using the discontinuous Galerkin spectral element method code, cmt-nek. We validate state-of-the-art drag models for a particle in an unsteady compressible flow and show good agreement, particularly at lower volume fractions. We model the particle bed as a nozzle or area reduction and, using isentropic flow relations, predict the final pressure, temperature, and Mach number extremely well in each case.
