Feedback control of vortex shedding using a resolvent-based modelling approach
Bo Jin, Simon J. Illingworth, Richard D. Sandberg
An investigation of optimal feedback controllers' performance and robustness is carried out for vortex shedding behind a 2D cylinder at low Reynolds numbers. To facilitate controll…
Linear control of coherent structures in wall-bounded turbulence at Re
Stephan F. Oehler, Simon J. Illingworth
We consider linear feedback flow control of the largest scales in an incompressible turbulent channel flow at a friction Reynolds number of Re = 2000. A linear model is formed…
Model-Based Estimation of Vortex Shedding in Unsteady Cylinder Wakes
Jiwen Gong, Jason P. Monty, Simon J. Illingworth
This paper considers single-sensor estimation of vortex shedding in cylinder wakes at in simulations and at in experiments. A model based on harmonic decompositi…
Streamwise-constant large-scale structures in Couette and Poiseuille flows
Simon J. Illingworth
The linear amplification mechanisms leading to streamwise-constant large-scale structures in laminar and turbulent channel flows are considered. A key feature of the analysis is th…
