Analysis of Pressure Coefficient in Airfoil Aerodynamics

The pressure coefficient along an airfoil is a crucial parameter in aerodynamics and plays a significant role in understanding and analyzing the aerodynamic performance of the airfoil. The pressure coefficient (Cp) is defined as the difference between the local pressure and the free-stream pressure, normalized by the dynamic pressure of the free stream. It is typically used to characterize the pressure distribution around an airfoil. In a wind tunnel, researchers and engineers conduct experiments to measure the pressure distribution around an airfoil. These experiments provide valuable data on the aerodynamic characteristics of the airfoil, and the pressure coefficient is a key parameter that is derived from these measurements.
