In aerodynamics, the pressure coefficient (Cp) is a dimensionless parameter that characterizes the pressure distribution on an object’s surface with respect to the ambient pressure of the flow. It provides valuable insights into the aerodynamic behavior of the object.
- (Cp) is the pressure coefficient
- 𝜃c is the half-angle of the cone.
The expression Cp = 2 * sin^2(𝜃c) describes the pressure distribution on the surface of a conical hypersonic body. It shows that the pressure coefficient varies along the surface, with maximum pressure occurring at the widest part of the cone (𝜃c = 90 degrees) and pressure equal to ambient at the apex (tip) of the cone (𝜃c = 0).
