Abstract:In this paper, the time-averaged and instantaneous information of the vaporized kerosene jet injection into a quiescent atmospheric environment, including the expansion angle, deflection angle and shock wave structure, were acquired by natural light and a schlieren system. The results show that the jet expansion angle increases first and then decreases during the kerosene vaporization, which is mainly governed by the pressure change inside the shear layer and the variation in the jet axial speed. Compared with… Show more
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.
