Abstract

Open and closed-loop control of a turbulent mixing layer is experimentally performed in a dedicated wind-tunnel facility (TUCOROM). The flow is manipulated with fluidic micro-valve actuators integrated in the trailing edge of the splitter plate. Sensing is performed using a rake of hot-wire probes located downstream in the mixing layer. The control goal is manipulation of the spreading rate and of the virtual origin of the mixing layer. The underlying physical mechanisms employ a wide range of frequencies as well as a wide range of spanwise modes. The calculated Reynolds number based on vorticity thickness is about Re = 2000. Control authority is presented with PIV and hot-wire results.
