The pressure coefficient behind an oblique shock wave is a dimensionless quantity that measures the relative change in pressure on the surface of a body due to the oblique shock wave that forms when the body is at an angle to the supersonic or hypersonic flow.
- Pressure coefficient (Cp)
- Specific heat ratio (𝛾)
- Oblique shock angle (β) in rad
- Mach number of the flow behind of the shock (M1)
