Large eddy simulations of turbulent flows on graphics processing units: application to film-cooling flows
… cooling at the surface. To counteract this, a micro-ramp vortex generator was added downstream of the film-cooling jet, which generated near-wall counter-rotating vortices of opposite sense to the vortex pair in the jet. It was found that the micro-ramp vortices created a downwash effect toward …

Large eddy simulation of shock boundary layer interaction control using micro-vortex generators
… a novel type of flow control device called micro-vortex generators (µVGs) which may offer similar control benefits without the bleed penalties. µVGs have the ability to alter the near-wall structure of compressible turbulent boundary layers to provide increased mixing of high speed fluid …

Active Flow Control of Subsonic Flow in an Adverse Pressure Gradient Using Synthetic Jets and Passive Micro Flow Control Devices
… the passive flow control elements such as micro-ramps with active flow control devices such as synthetic jets to achieve higher control authority.</p><p>The goal of this dissertation is twofold. The first objective is to assess the ability of CFD with URANS turbulence models to accurately …

Numerical and experimental investigation of VG flow control for a low-boom inlet
… VG) case that was substantially broken up in the micro-ramp VG case, consistent with simulations. Furthermore, the predicted subsonic VG performance with respect to a reduction in radial distortion (quantified in terms of axisymmetric incompressible shape factor) was found to be consistent with …
