Submitted for the DFD12 Meeting of The American Physical Society Mechanism of axis-switching in low aspect-ratio rectangular jets NAN CHEN, HUIDAN (WHITNEY) YU, Indiana University-Purdue University Indianapolis (IUPUI) — Axis-switching (AS) refers to the change in the orientation of the major axis of the jet from initial spanwise to later lateral direction. This phenomenon is of great interest ...

Temporal flow control of a jet has been widely studied in the past to enhance jet mixing or reduce jet noise. Most of this research, however, has been done using small diameter low Reynolds number jets that often have little resemblance to the much larger jets common in real world applications because the flow actuators available lacked either the power or bandwidth to sufficiently impact these...
