Design of a shock-induced combustion experiment in an axisymmetric configuration with hydrogen injection
conference paper
This work presents a design for a shock-induced combustion experiment using a two-angle cone configuration. Three injector geometries were considered: a cone surface, a dual stage configuration with rectangular gaps (DSRG) and a cylindrical ramp (CR). Four parameters were investigated: the penetration height, the mixing efficiency, the control of premature ignition and the shock wave / boundary layer interaction. The numerical calculations were performed with the Fluent™ code, using the density-based coupled-implicit solver. The hydrogen-oxygen combustion was modeled with a 9 species / 20 reactions Jachimowski mechanism. The CR injector dispersed the hydrogen far from the wall and thus gave the best fiowfield for shock-induced combustion. The reactive portion revealed that combustion can be initiated by the second shock, but under certain conditions, combustion occurs in a subsonic region.
