This book is an introduction to machine learning control (MLC), a surprisingly simple model-
free methodology to tame complex nonlinear systems. These systems are assumed to be …

A combination of passive and active methods is used to manipulate the symmetry of the
turbulent wake of an Ahmed body. Dedicated experiments to study the wake reversals …

The wake dynamics of a rectangular flat-backed bluff body is studied using both the wind
tunnel experiment and Improved Delayed Detached Eddy Simulation (IDDES) at Re= 9.2× …

We present the first machine-learned multiple-input multiple-output aerodynamic feedback
control under varying operating conditions. Closed-loop control is relevant to many fluid …

We stabilize the flow past a cluster of three rotating cylinders–the fluidic pinball–with
automated gradient-enriched machine learning algorithms. The control laws command the …

Innovations in fluid mechanics have been leading to better food since ancient history, while
creativity in cooking has inspired fundamental breakthroughs in science. This review …

Improved turbulence modeling remains a major open problem in mathematical physics.
Turbulence is notoriously challenging, in part due to its multiscale nature and the fact that …

The dynamics of the wake behind a flat-back Ahmed body are modified using a large-scale
fluidic oscillator, aiming at drag reduction and the reflectional symmetry breaking (RSB) …

The bi-modal behaviour of the turbulent flow past three-dimensional blunt bluff bodies is
simulated using wall-resolved large eddy simulations. Bi-modality (also called bi-stability) is …

We investigate open-and closed-loop active control for aerodynamic drag reduction of a car
model. Turbulent flow around a blunt-edged Ahmed body is examined at Re_ H ≈ 3 * 10^ 5 …
