Numerical simulation of unsteady viscous flow around an airfoil with oscillating spoiler

摘要

Numerical simulations of unsteady viscous flows around an airfoil with oscillating spoiler have been performed using the compressible Navier-Stokes equations. The Yee-Harten Total Variation Diminishing (TVD) scheme and the Baldwin-Lomax algebraic turbulence model are employed. The unsteady pressure distributions on the 16 percent thick supercritical airfoil with oscillating spoiler in low subsonic and transonic Mach numbers have been calculated, being compared with the existing experimental data.
