Feedback Control of Turbulent Shear Flows by Genetic Programming
Thomas Duriez, Vladimir Parezanović, Kai von Krbek +14
Turbulent shear flows have triggered fundamental research in nonlinear dynamics, like transition scenarios, pattern formation and dynamical modeling. In particular, the control of…
Upstream open loop control of the recirculation area downstream of a backward-facing step
Nicolas Gautier, Jean-Luc Aider
The flow downstream a backward-facing step is controlled using a pulsed jet placed upstream of the step edge. Experimental velocity fields are computed and used to the recirculatio…
Closed-loop separation control using machine learning
Nicolas Gautier, Thomas Duriez, Jean-Luc Aider +3
A novel, model free, approach to experimental closed-loop flow control is implemented on a separated flow. Feedback control laws are generated using genetic programming where they…
Experimental Feed-Forward Control of the Backwards-Facing Step Flow
Nicolas Gautier, Jean-Luc Aider
Closed-loop control of an amplifier flow is experimentally investigated. A feed-forward algorithm is implemented to control the flow downstream a backward-facing step. Upstream and…
Frequency lock closed-loop control of a separated flow using visual feedback
N. Gautier, J. -L. Aider
In this study, a simple model based closed-loop algorithm is used to control the separated flow downstream a backward-facing step. It has been shown in previous studies that the re…
Experimental study of Counter-Rotating Vortex Pair Trajectories induced by a Round Jet in Cross-Flow at Low Velocity Ratios
T. Cambonie, N. Gautier, J. -L. Aider
Circular flush Jets In Cross-Flow were experimentally studied in a water tunnel using Volumetric Particle Tracking Velocimetry, for a range of jet to cross-flow velocity ratios, r,…
Control of the flow behind a backward-facing step by visual feedback
N. Gautier, J-L. Aider
The separated flow downstream a backward-facing step is controlled using visual information for feedback. This is done when looking at the flow from two vantage points. Flow veloci…
Real-time planar flow velocity measurements using an optical flow algorithm implemented on GPU
N. Gautier, J-L. Aider
This paper presents a high speed implementation of an optical flow algorithm which computes planar velocity fields in an experimental flow. Real-time computation of the flow veloci…
