We study the influence of an array of air-jet vortex generators on a 24o compression-ramp interaction at Mach 2.5 and a free stream unit Reynolds number of Re/m= 9.72× 106. Focusing-schlieren and oil-flow visualisation were used to characterise the flow features, while particle image velocimetry was used to study the mean flow and turbulence of the interaction region. Further interpretation was carried out based on a snapshot proper orthogonal decomposition of the velocity fields for the baseline and the control cases, extracting the energetic coherent structures of the flow. The injection of the jets was found to redistribute the energy from the lower order modes to the higher order modes, while maintaining nearly similar structural distribution as the baseline case.
