Part of the International Union of Theoretical and Applied Mechanics book series (IUTAM)


The unsteady compressible Reynolds time averaged Navier-Stokes equations which include an algebraic turbulence model have been applied to an oscillating airfoil in turbulent flow. The governing equations are written in conservation form in a body fitted coordinate system and solved using an Alternating Direction Implicit (ADI) procedure. Results are presented for turbulent flow about NACA 0012 and the ONERA-CAMBRÉ airfoils whose incidence oscillate from 0 degree to 20 degrees. The effects of reduced frequency and leading edge camber on the normal force and pitching moment coefficients are analyzed and qualitatively good agreement has been obtained with experimental data.
