Abstract
Derived from literature, the use of a single symmetric triangular strut, oriented along the centerline of a Supersonic RAM (SCRAM) jet combustion chamber, is an effective approach to the challenge of generating turbulence within low supersonic free streams. Authors have explored methods of improving the mixing and combustion efficiency of this scheme by optimizing the strut geometry, increasing the number of struts, and altering the angle of hydrogen fuel injection from the aft strut face. This study aims to explore the combined effect of multiple struts and angled fuel injection at 45° from centerline, on mixing efficiency. Simulations were performed using Ansys-Fluent. Computational approaches to flow, chemistry, and turbulence modeling were validated through comparison with experimental and computational data available in literature. Although the magnitude of turbulence generated by the scheme has the potential of mixing and dissipating hydrogen on a similar scale to parallel injection, more data is needed to fully define the scheme’s capabilities.
