摘要

This article fully investigates the hydrogen fuel jet mixing behind the strut with a serpentine injector at a supersonic combustion chamber. The main goal of this work is to analyze the three-dimensional flow of hydrogen jet released from the serpentine nozzle by computational technique. The role of serpentine nozzle height is also examined to find the optimum location for fuel mixing. Meanwhile, the extruded serpentine nozzle located behind the strut is also studied. The strength of circulation in these configurations is compared and our results show that the fuel circulation strength is improved when the serpentine nozzle is located in a higher height behind the strut. Moreover, a comparison of the fuel mixing behind the strut indicates this injector has significantly higher fuel mixing efficiency (about 40%) in comparison with a circular nozzle.
