Direct numerical simulations of transonic wings at moderate Reynolds numbers —

Direct numerical simulations around Dassault Aviation's V2C airfoil were carried out at a Reynolds number Re=500,000 and a Mach number M=0.7. The movie shows vorticity contours in red and blue, and strong pressure gradients in the background. A wide range of instabilities is observed.
