Abstract

We experimentally investigated the effect of orifice geometry on the characteristics of a transversely injected liquid jet into a supersonic crossflow. The focus was to highlight the role of orifice inlet shape on the liquid jet penetration and associated bow shock dynamics. It was found that for a given momentum flux ratio, the liquid jet from a sharp-edged nozzle exhibits higher jet penetration and bow shock strength compared to that from a tapered inlet nozzle. High-speed shadowgraphy images show that the observed variation in the jet penetration and bow shock position is due to strong shock wave�boundary layer interaction in the flow. Quantitative measurements of the jet penetration height and shock fluctuations are obtained for both nozzles. The fluctuations of liquid jet injected through the tapered inlet nozzle have significantly higher in the spatial extent compared to that of the sharp-edged nozzle. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
