Effect of rotation on coherent structures in wall-bounded turbulence

Proper orthogonal decomposition (POD) is applied to a rotating channel turbulence database generated by direct numerical simulation (DNS) to investigate the effect of spanwise rotation on the coherent structures in wall-bounded flows. The POD analysis reveals the appearance of elongated counter-rota...
