AERODYNAMIC LOADS MEASUREMENTS ON AN AIRFOIL USING PIV SYSTEM

摘要

An assessment of applicability of using PIV-velocity data for the nonintrusive aerodynamic force characterization (lift and drag) of an airfoil is made. The method of the control volume based on integration of hydrodynamic variables along the closed contour around an airfoil was used for calculations. The results of these calculations were compared with results of standard pressure-based lift coefficient measurements (surface pressure distribution and wake rake).
