Quality Assessment in LES of a Compressible Swirling Mixing Layer

Part of the Ercoftac Series book series (ERCO, volume 12)

We apply large-eddy simulation (LES) to simulate the nonlinear evolution of a subsonic circular swirling mixing layer, a round jet surrounded by slow co-flow with an additional swirl component present only in the narrow shear layer. The growth of viscous spatial instabilities and transition to turbulence of the swirling mixing layer are investigated. LES results are assessed at different resolutions and compared with reference results from direct numerical simulation (DNS).
