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…
