Nonlinear evolution of the centrifugal instability using a semi-linear model
Eunok Yim, Paul Billant, Francois Gallaire
We study the nonlinear evolution of the centrifugal instability developing on a columnar anticyclone with a Gaussian angular velocity using a semi-linear approach. The model consis…

Optimal spanwise-periodic control for recirculation length in a backward-facing step flow
E. Yim, I. Shukla, F. Gallaire +1
Three-dimensional control is considered in the flow past a backward-facing step (BFS). The BFS flow at Reynolds number (defined with the step height and the maximum inlet…
