Next: Appendix: Oblique Shock Stability Up: Oblique Shock Previous: Retouch of Shock or Index SummaryAs with normal shock, the oblique shock with upstream Mach number, is always greater than 1. However, in oblique, as oppose to the normal shock, the downstream Mach number, could be larger or smaller then 1. The perpendicular component of the downstream Mach number, is always smaller than 1. Given and the deflection angle, there could be three solutions: the first one is the ``impossible'' solution in the case where D is negative, two is weak shock, and three is strong shock. When D is positive there is no physical solution and only normal shock exist. When D is equal to zero, a special case is created because the weak and strong solutions are equal (for large deflection angle). When , for large deflection angle, there is a possibility of no two-dimensional solution resulting in a detached shock case.
