Abstract

This paper presents the results of an ongoing experimental and numerical investigation into the unsteady process of blast wave reflection from straight smooth surfaces. Basic blast wave phenomena such as the transition from regular to irregular wave reflection can be adequately and conveniently studied in a laboratory environment by using small charges with masses in the milligram range. Previous work [1] has already revealed considerable discrepancies between numerical and experimental results for the location xtr of the transition from regular to irregular wave reflection. Further experiments with improved diagnostics confirm that the experimental determination of the transition point is rather difficult and possibly inaccurate because of the initially minuscule size and gradual growth of the Mach stem.
