Abstract

The propagation of converging polygonal shock waves are documented using schlieren photography in order to compare with geometrical shock dynamics. Shock waves shaped as symmetric polygons of 6, 8 and 12 sides are created in a shock tube. The results are compared with the theoretical predictions and show good agreement.
