Effect of wall mounted three dimensional cavities on the mixing of gaseous injectant based on the entrainment of secondary jet into the primary supersonic flow of Mach number 1.7 is studied. Mixing induced by flow unsteadiness and exchange of fluid between the cavity and main stream flow has been investigated. In order to study the influence of the ratio of cavity length to width (L/W) for constant length to depth ratio (L/D) on the fluid dynamic behaviour, three cavities of L/W ratios between 2 and 4 were used in the study. Acoustic oscillations generated from the cavity were observed to have profound impact on mass exchange between the cavity and the freestream flow. These acoustic oscillations which govern the flow unsteadiness were in turn found to be dependent on the L/W ratio of the cavity. Shift in dominant acoustic mode was observed as the L/W ratio was changed from 3 to 4. Entrainment of secondary injected jet into the primary M=1.7 flow was observed to vary with cavity width quantitatively. The trend in this variation depended on the amplitude of acoustic oscillations generated by the cavities.
