Gauging Centrifugal Instabilities in Compressible Free-Shear Layers Via Nonlinear Boundary Region Equations
Omar Es-SAhli, Adrian Sescu, Yuji Hattori
Curved free shear layers emerge in many engineering problems involving complex flow geometries, such as the flow over a backward facing step, flows with wall injection in a boundar…
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…
Investigation of wakes generated by fractal plates in the compressible flow regime using large-eddy simulations
Omar Es-Sahli, Adrian Sescu, Mohammed Z. Afsar +1
We investigate flows interacting with a square and a fractal shape multi-scale structures in the compressible regime for Mach numbers at subsonic and supersonic upstream conditions…
