Characteristics of flow While the definition of hypersonic flow can be quite vague and is generally debatable -LRB- especially due to the lack of discontinuity between supersonic and hypersonic flows -RRB- , a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow .

A hypersonic flow may be characterized by certain things that can no longer be discounted in analysis .
