Abstract : Following the successful application of the HULL code to the modelling of shock waves colliding with a smooth planar surface, as described in a previous report, the influence of collision angle on reflection type was investigated. The numerical investigations revealed examples of both regular and Mach reflection. From these an estimate of the transition collision angle for a non-decaying air shock wave of M sub I = 1.472 (overpressure of 137.9 kPa) was made. This angle was found to be approximately 41.5 deg.
