Characteristics of Flow
While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the lack of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow. The peculiarity in hypersonic flows are as follows:
- Shock layer
- Aerodynamic heating
- Entropy layer
- Real gas effects
- Low density effects
- Independence of aerodynamic coefficients with Mach number.
