Abstract

A simplified analytical model of the Mach reflection of a planar shock wave over a concave cylindrical wedge has been used to predict the triple point trajectory and the triple point trajectory angle at glancing incidence. Comparison with experimental results suggests that the simplified approach for predicting the triple point trajectory is good for an incident shock wave Mach number, M_i, less than 1.1. However, the prediction of the triple point trajectory angle at glancing incidence is good for any value of M_i as long as the assumption of a perfect gas is valid.
