A test facility featuring jet(s) in cross flow con-figuration is presented. The peculiarity of the rig stems from the presence of an acoustic forcing sys-tem that introduces planar acoustic waves in the cross flow. Microphones, PIV and LDV measure-ments have been conducted in forced and unforced configurations. The experimental database built so far already gives the possibility of assessing in depth the predictive capability of related steady or unsteady simulations.
