A Control Forced Concurrent Precursor Method for LES Inflow
John Haywood, Adrian Sescu
With the increased application of large eddy simulation techniques, the generation of realistic turbulence at inflow boundaries is crucial for the accuracy of a simulation. The Con…
Effect of Wall Transpiration and Heat Transfer on Nonlinear Görtler Vortices in High-speed Boundary Layers
Adrian Sescu, Radwa Alaziz, Mohammed Afsar
Görtler vortices in boundary layer flows over concave surfaces are caused by the imbalance between centrifugal effects and radial pressure gradients. Depending on various geometric…
Assessment of the impact of two-dimensional wall deformations' shape on high-speed boundary layer disturbances
Jeremy Sawaya, Vasileios Sassanis, Sofia Yassir +2
Previous experimental and numerical studies showed that two-dimensional roughness elements can stabilize disturbances inside a hypersonic boundary layer, and eventually delay the t…
Iterative control of Görtler vortices via local wall deformations
Adrian Sescu, Lamiae Taoudi, Mohammed Afsar
Görtler vortices develop along concave walls as a result of the imbalance between the centrifugal force and radial pressure gradient. In this study, we introduce a simple control s…
Hampering Görtler vortices via optimal control in the framework of nonlinear boundary region equations
Adrian Sescu, Mohammed Afsar
The control of stream-wise vortices in high Reynolds number boundary layer flows often aims at reducing the vortex energy as a means of mitigating the growth of secondary instabili…
