Abstract
We computed the base, instantaneous and mean flow around a micro-ramp immersed in an incompressible boundary layer. Results of our Direct
Numerical Simulations (DNS) are compared with an independent stability analysis and experiments. We analyse flow structures and mechanisms that contribute to the micro-ramp functionality and find that transitional perturbations increase the near-wall momentum in the mean flow more efficiently than the primary vortices in the laminar base flow.
