Effect of a Pylon Mounted Cavity-Based Flameholder on ‎the Combustor Flow Characteristics

This paper aims to study the effect of a pylon mounted cavity-based flameholder on the combustor flow ‎characteristics. Computational analysis of two different models of flameholder configurations is ‎performed. The novel cavity design 110_90 has a fore-wall ramp angle of 110 degrees and an aft-wall...
