The pressure coefficient behind an oblique shock wave is a measure of the change in pressure across the shock wave. It is a dimensionless quantity that provides information about how the pressure changes as a fluid flows through the shock wave.

- Pressure coefficient (Cp)
- Specific heat ratio (𝛾)
- Oblique shock angle (β) in rad
- Freestream Mach number of the flow behind of the shock (M∞)
