Closed-loop turbulence control is a critical enabler of aerodynamic drag reduction, lift
increase, mixing enhancement, and noise reduction. Current and future applications have …

▪ Abstract We review the direct numerical simulation (DNS) of turbulent flows. We stress that
DNS is a research tool, and not a brute-force solution to the Navier-Stokes equations for …

The ability to actively or passively manipulate a flow field to bring about a desired change is
of immense technological and economical importance. This volume provides a thorough, up …

In this review, we present control methods for flow over a bluff body such as a circular
cylinder, a 2D bluff body with a blunt trailing edge, and a sphere. We introduce recent major …

This is a book on Optimal Control Problems (OCPs): how to formulate them, how to set up a
suitable mathematical framework for their analysis, how to approximate them numerically …

This book provides a comprehensive treatment of a very successful class of methods for
solving optimization problems with PDE and inequality constraints as well as variational …

Direct numerical simulations (DNS) and optimal control theory are used in a predictive
control setting to determine controls that effectively reduce the turbulent kinetic energy and …

The goal of this paper is to provide a perspective on the current status and future directions
for active flow-control technology with particular emphasis on oscillatory control. This is not a …

This brief article reviews the important advances in the field of flow control that took place
during the past few years. This broad area of research remains of great interest for its …
