Explorative gradient method for active drag reduction of the fluidic pinball and slanted Ahmed body Open
We address a challenge of active flow control: the optimization of many actuation parameters guaranteeing fast convergence and avoiding suboptimal local minima. This challenge is addressed by a new optimizer, called the explorative gradien…

Optimization of active drag reduction for a slanted Ahmed body in a high-dimensional parameter space Open
We numerically optimize drag of the 35° slanted Ahmed body with active flow control using Reynolds-Averaged Navier-Stokes simulations (RANS). The Reynolds number is Re_H = 1.9 x 10^5 based on the height of the Ahmed body. The wake is contr…
