This paper presents the results of an experimental study of the flowfield characteristics of the interaction of two two-dimensional jets impinging against a normal ground plane. The flowfield was observed visually using oil-flow patterns. Measurements of turbulence and averaged velocities in the flowfield were performed. Parameters included in this investigation were the distance from the ground plane and the jet relative strength. The response of the flowfield to the variation in these parameters has been characterized. Increasing the distance between the jet exit plane and the ground plate, the developed stagnation pressure in the upwash formation region exceeds those corresponding to the jet central streamline. It is found that, in a two-impinging-jet flow, the rate of jet decay is higher than that for a single jet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
