Shock Waves: 26th International Symposium on Shock Waves, Volume 2, 2009•SpringerAn experimental investigation of the flow behind a shock diffracting over faceted walls with
turning angles for individual facets of 22.5° and 30° has been conducted at an incident
shock Mach number of 1.5. The features of the near wall flow have been identified and the
early development of the flow around the wall was considered. For the Mach 1.5 case, the
expansion generated at each corner was shown to have a marked effect on the separation
shear layers formed after each corner. More work needs to be done using a less …

Summary
An experimental investigation of the flow behind a shock diffracting over faceted walls with turning angles for individual facets of 22.5° and 30° has been conducted at an incident shock Mach number of 1.5. The features of the near wall flow have been identified and the early development of the flow around the wall was considered. For the Mach 1.5 case, the expansion generated at each corner was shown to have a marked effect on the separation shear layers formed after each corner. More work needs to be done using a less directionally sensitive optical system.
