Abstract

Active control of sublayer streak bursting in artificially excited turbulent spots in a water channel was experimentally performed. Flow-aligned surface heating elements were used as activators to input controlled velocity perturbations into the near-wall region in response to the presence of a detected low-speed streak. It was found that when active control was applied, significant reductions in both turbulence intensity and Reynolds stress production were measured.
