The pressure coefficient at point A, denoted as “Cp,A,” is a dimensionless parameter used in fluid dynamics and aerodynamics to describe the local pressure distribution at a specific location or point within a fluid flow field, usually on the surface of an object like an airfoil or aircraft wing. Cp,A provides insight into how the pressure at that particular location compares to the freestream (ambient) pressure and is an essential parameter for understanding the aerodynamic behavior of an object.Â
