Reconsideration of the Shock-Shock Relations for the Case of a Non-Quiescent Gas ahead of the Shock and Verification with Experiments

The three-dimensional shock-shock relations for the case in which the shock structure propagates in a non-quiescent gas are developed. The developed model equations are found to be different from those of another model developed by Han & Yin (1993), due to an error which they introduced into their model. Predictions based on both models are compared to experimental results. The predictions of the model developed in the course of the present study are found to be better than those of Han & Yin's (1993) model. This fact could be used as a verification of the fact that there is indeed an error in Han & Yin's (1993) model.
