SUMMARY:Active Control of Fluid-Structure Interaction Systems
DESCRIPTION:Lecturer:Assoc. Prof. Hui Tang\n Faculty:Department of Mechanic
 al Engineering\n Institute:The Hong Kong Polytechnic University\n Location
 :Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstra
 ct: \n Details: \n In this talk\, the use of active control to change the 
 dynamics of idealized fluid-structure interaction (FSI) systems will be in
 troduced. Here the term "active control" means that the control is realize
 d by injecting a small amount of energy into existing FSI systems. Compare
 d to its counterpart\, i.e.\, passive control\, active control is adaptive
  and on-demand\, and hence has a much wider operating range.\nFirst\, the 
 control of wakes and vortex-induced vibrations of a circular cylinder usin
 g synthetic jets (SJs) will be introduced. As an associated phenomenon\, l
 ock-on of vortex shedding to a pair of SJs will be discussed.\nSecond\, en
 hancement of flapping-foil aerodynamics using various active control metho
 ds\, including SJs\, leading-edge perturbations and adjustable flexibility
 \, will be presented.\nLast\, the adoption of machine-learning methods on 
 active closed-loop control of a cylinder flow system will be demonstrated.
