DNS-Investigations of the Development and Control of Crossflow Vortices in a 3-D Boundary-Layer Flow

  • Conference paper
Laminar-Turbulent Transition

Part of the book series: IUTAM Symposia ((IUTAM))

Abstract

The development and control of steady crossflow-vortex (CFV) packets in a laminar 3-d flat-plate boundary-layer flow is investigated by means of spatial Direct Numerical Simulations based on the complete incompressible 3-d NavierStokes equations. The boundary-layer flow is generic for an infinite swept wing, with favorable and ensuing adverse chordwise pressure gradient. The CFV packets investigated represent disturbances generated either by a spanwise row of bulges or dents. First, the respective downstream growth with nonlinear effects is simulated. Second, the active downstream control by different control strategies, and the effect of a passive, steady upstream 3-d flow deformation (UFD) is investigated in detail.
