A Lagrange multiplier-based optimal control technique for streak attenuation in high-speed boundary layers
Omar Es-Sahli, Adrian Sescu, M. Z. A. Koshuriyan +2
High-amplitude free stream turbulence and surface roughness elements can excite a laminar boundary layer flow sufficiently to cause streamwise oriented vortices to develop. These v…

Investigation of Görtler vortices in high-speed boundary layers via an efficient numerical solution to the non-linear boundary region equations
Omar Es-Sahli, Adrian Sescu, Mohammed Afsar +1
Streamwise vortices and the associated streaks evolve in boundary layers over flat or concave surfaces due to disturbances initiated upstream or triggered by the wall surface. Foll…
