Correlation of Separation Angles Induced by Glancing Interactions

In this study, angles of primary separation lines induced by three disparate familes of shock generators - unswept sharp fins, semi-cones, and swept triangle fins - are emphasized, and relationships among the three families are investigated by considering the inviscid pressure field in the interaction region. A correlation law useful for predicting the separation angles, which takes into account the shock-curvature effect, is then postulated.
