Abstract

Numerical simulations of dynamic–stall phenomena have been performed using an implicit unfactored Navier–Stokes solver and various turbulence closures, including linear and nonlinear low–Re eddy–viscosity models. The accuracy of the models has been assessed against a range of experimental data for ramping and oscillating aerofoils at subsonic and transonic conditions. The computations indicate that the nonlinear eddy–viscosity models better predict the shedding of the dynamic–stall vortex and the unsteady aerodynamic loads.
