The pressure coefficient, denoted as “Cp,” is a dimensionless parameter used in fluid dynamics and aerodynamics to describe the pressure distribution around an object immersed in a fluid flow. It is a normalized measure of the pressure at a particular point on the object relative to the freestream dynamic pressure of the fluid.
- Cp: Pressure coefficient
- p: Pressure at a specific point on the object
- p∞: Static pressure of the freestream flow (the pressure far away from the object, where the flow is undisturbed)
- q∞: Dynamic Pressure
