摘要	In this study, the numerical analysis of the three-dimensional flow fields of a series of tandemarranged equal-strength hydrogen jets injected into a Mach 8 hypersonic crossflow is presented. The study comparatively analyzes the flow field similarities and differences between different configurations, namely, single, double, and quadruple jets. The results indicate that downstream jets do not have a significant effect on the first Mach cell and only slightly lift the bow shock at downstream compared with the single jet case. Additionally, high-temperature regions in all cases are in close proximity to the hydrogen stoichiometric equivalence ratio interface, making the fuel more prone to pre-ignition. Moreover, flow patterns in inter-gap regions and vortex structures are compared casewise. In addition, hydrogen injected from each orifice is traced, and the mass fraction distribution contributed by each jet on the symmetry plane and the inter-gap region is analyzed to derive the mixing characteristics. & COPY; 2023 Elsevier Masson SAS.
