The scope of this study is to examine the effect of chevrons on the flow and acoustic properties of the supersonic free jet by comparing CD nozzles of three different configurations: baseline, 6-chevrons, and 12-chevrons. Experiments were conducted for various NPRs ranging from 2.25 to 4.25, using the blow-down supersonic wind tunnel. The flow visualization was done with a Schlieren setup and the acoustic signature was captured using a sound level meter at various observation points from the jet. Visualization images indicate that the chevrons alter the free-jet structure of the supersonic flow by reducing the shock cell length and adding streamwise vortices to the flow. Acoustic analysis reveals that both chevron nozzle configurations accomplish significant noise mitigation compared to the baseline nozzle; the 12-chevron configuration mitigates noise better at NPR 2.25, while the 6-chevron configuration shows superior performance at NPR 2.75 and 3.25.
