Abstract

This chapter presents experimental and numerical work in progress on shock propagation through dust columns in a shock tube environment. The shock tube consists of a short double driver chamber separated by membranes from the driven section. The shock tube is instrumented with pressure sensor and high-speed cameras. A specially designed window section allows Schlieren and shadow photography to be recorded simultaneously, in directions perpendicular to each other. The dust column is injected from below in the driven section, using a spark generator. The timing is such that the dust is in suspension before the shock arrives. The numerical method Regularized Smoothed Particle Hydrodynamics has been used to simulate shock–dust interaction problems, with a full multiphase description. Comparison with experimental data shows promising results for further studies on shock–dust interactions.
