WebbI am a researcher at the German Aerospace Center (DLR) in the spacecraft department focusing on aerodynamics and fluid mechanics of rocket powered vehicles using numerical simulation. The main areas of my research involve elements of solid rocket propulsion (multi phase flow, reactive flow, rocket plume modelling) and aerothermodynamics of … Webb11 apr. 2024 · Liu et al. 9 founded that a bump structure can reduce losses induced by the first passage shock and boundary layer separation in a supersonic cascade with high incoming Mach number. The bump structure can reduce losses by 4.6%. Another control mode is to inject fluid into the mainstream or to remove low-energy fluid from mainstream.
