The work presented focuses on high-accuracy numerical studies to examine the effect of freejet upstream flow conditions on flow-acoustic resonant interactions in the transitional regime for a cambered SD7003 airfoil. Numerical studies employ a 6th-order Navier-Stokes solver implementing low-pass filtering of poorly resolved high-frequency solution content to retain numerical accuracy and stability over a range of transitional flow regimes. A 2D comparison of uniform vs. freejet upstream flow conditions is first present to investigate the effect of the nozzle and the developing shear layer on the acoustic radiation field. In addition, preliminary 2D vs. 3D ILES freejet simulations are investigated to allow for further examination of the underlying physics associated with the freejet and its overall impact on the flow-acoustic resonant interactions.
