Abstract

Stabilizing combustion in supersonic flows is a formidable challenge due to the small time scales afforded for air-fuel mixing. Numerous studies in this area have demonstrated the potential of strut-style platforms for fuel injection and mixing enhancement, which remains an active area of research. In the Aerodynamics Research Laboratory at Missouri S&T, a strut-style injector system has recently been installed. In this study, we characterize the flow structures behind this platform in a range of injection pressures and corresponding mass flux ratios. The wake generated by a strut and injection plume, even absent combustion or mixing enhancement geometry, has an appreciable impact on the resulting air-fuel mixing. This motivates its characterization. Tomographic Particle Image Velocimetry (Tomo-PIV) is utilized to capture the flow field downstream of the strut injector platform in a measurement region spanning 50 x 140 x 10mm. This work expands the current body of literature on the effects of strut platforms in supersonic flows and will allow future studies to delineate the structures generated by base platform injection from those caused by trailing edge modifications.
