Keywords: vortex generator, turbulence generator, iddes
Passive flow control methodologies, such as vortex generator and roughness, are investigated using SST-IDDES. After applying the flow control methodologies, the recirculation behind the backward facing step becomes smaller, the buffet region over the supercritical airfoil is greatly suppressed and the transition is successfully triggered.
