Flows with Strong Shocks
From this chapter on, we turn to the presentation of hypersonic flow theory, that is, the theory of the flowswith highMach numbers,M∞ 1. In particular, the chapter is devoted to the flow past bodies in the presence of strong shocks. This circumstance, which often makes the physics of the phenomenonmore difficult, at the same time facilitates the purely gas dynamic analysis due to the corresponding simplification of the governing equations. This simplification is based on the use of some small parameters whose appearance is due to strong shock waves accompanying hypersonic flows. At the same time, it turns out that many properties of these flows can be carried over to moderately supersonic flows.
