The maximum pressure coefficient (Cp,max) is a dimensionless quantity that measures the highest relative pressure difference between a point on the surface of a body and the free-stream pressure in a fluid flow field. The maximum pressure coefficient can be used to calculate the aerodynamic forces and moments acting on a body in various flow regimes, such as subsonic, supersonic, or hypersonic flows.
- Maximum pressure coefficient (Cp,max)
- Specific heat ratio (𝛾)
- Freestream Mach number (M∞)
- Ratio of pressure behind the normal shock to the freestream pressure (p0,2/p∞)
