| Abstract: | Supersonic combustion experiments of a fixed entry Mach number 2.5 were conducted using eight model combustors, at various stagnation conditions and global equivalence ratio. Effects of wall injection, strut injection, and cavity flameholder were systematically investigated. A one-dimensional model was further proposed for data reduction and analysis. The calculated results are fairly consistent with the experimental measurements. Performance of various model combustor as well as the factors affecting combustion efficiency and total pressure recovery were discussed. |
