Computational Investigation of Multi-Strut Injection of Hydrogen in a Scramjet Combustor

Abstract Multi-strut injection is an approach to increase the overall performance of Scramjet while reducing the risk of thermal choking in a supersonic combustor. Hence numerical investigations of a hydrogen-fueled scramjet combustor at Mach 2.5 have been performed with a three struts combustor combining the central wedge strut as well as additional two wedge strut injectors. These numerical simulations are aimed to study the flow structure, supersonic mixing, and combustion phenomenon for the present combustor configurations. The presence of the multi strut injection improved the turbulent mixing and, consequently, the combustion process.
