The pressure coefficient for hypersonic flow across a normal shock wave is a dimensionless quantity that measures the relative change in pressure due to the shock wave. The pressure coefficient for hypersonic flow across a normal shock wave depends on the Mach number and the ratio of specific heats of the fluid.
- Pressure coefficient (Cp)
- Pressure behind the normal shock (p2) in N/m^2
- Freestream pressure (p∞) in N/m^2
- Freestream velocity (V∞) in m/s
