is the linearized pressure coefficient for incompressible flow, which quantifies the change in pressure at a specific point on an airfoil or aerodynamic surface relative to the freestream pressure. It is a dimensionless parameter. The linearized pressure coefficient is a dimensionless parameter that quantifies the change in pressure () at a specific point on an airfoil or aerodynamic surface relative to the freestream pressure () in incompressible flow.
- Prandtl-Glauert parameter (β)
- Horizontal perturbation velocity (ū) in m/s
- Freestream velocity (V∞) in m/s
