Active control of jets from indeterminate-origin nozzles
Abstract
Acoustic excitation has been applied to indeterminate-origin (IO) nozzles. The resulting highly three-dimensional instability-wave patterns generate complex vortex interaction systems. Phase-locked schlieren photography has been used to document major features of the flowfields generated from IO nozzles under active control
