Numerical Flow Visualization of Separated Flows Around Oscillating Airfoil by Solving Incompressible Navier-Stokes Equations
Numerical flow visualization of separated flows around oscillating airfoil are conducted by solving incompressible Navier-Stokes equations by a third-order upwind scheme in order to understand the flow structure and mechanism of dynamic stall. The calculated separated region is small in pitching-up process and it becomes large in a pitching-down process. Quite different characteristics of flow patterns between in a pitching-up and pitching-down processes are obtained.
