The deflection angle by applying the high Mach number limit is the angle by which the flow is turned by a shock wave or an expansion wave when the Mach number goes to infinity. In this limit, the deflection angle approaches zero, which means that the flow becomes nearly parallel to the wave.
- Deflection angle (θ) in rad
- Mach number of the flow ahead of the shock (M1)
- Shock angle (β) in rad
- Specific heat ratio (𝛾)
