Effects of Micro-Ramps on a Shock Wave/Turbulent Boundary Layer Interaction
39th AIAA Fluid Dynamics Conference, 2009 Stereoscopic particle image velocimetry is used to investigate the effects of micro-ramp sub-boundary layer vortex generators, on an incident shock wave/boundary layer interaction at Mach 1.84. Single- and double-row arrangements of micro-ramps are considered.

Flow-level coordination of connected and autonomous vehicles in multilane freeway ramp merging areas
Multimodal Transportation, 2022 On-ramp merging areas are deemed to be typical bottlenecks for freeway networks due to the intensive disturbances induced by the frequent merging, weaving, and lane-changing behaviors.

On Reynolds number dependence of micro-ramp-induced transition [PDF]
Journal of Fluid Mechanics, 2018 The variation of transitional flow features past a micro-ramp is investigated when the Reynolds number is decreased approaching the critical regime. Experiments are conducted in the incompressible flow spanning from supercritical to subcritical roughness-height-based Reynolds number ($Re_{h}=1170$, 730, 460 and 320) with tomographic particle image ...

Micro-Ramps for External-Compression Low-Boom Inlets [PDF]
39th AIAA Fluid Dynamics Conference, 2009 The application of vortex generators for flow control in an external compression, axisymmetric, low-boom concept inlet was investigated using RANS simulations with three-dimensional (3-D), structured, chimera (overset) grids and the WIND-US code. The low-boom inlet design is based on previous scale model 1- by 1-ft wind tunnel tests and features a zero-
