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 ‎ramp angle of 90 degrees and this design which shows a comparatively better combustor performance is ‎adopted and mounted with a pylon. The flow features over the high performance base cavity 110_90 is ‎compared with the flow features obtained by adding a pylon on the upstream of the base cavity. The two ‎cases are compared qualitatively as well as quantitatively based on the temperature distribution, pressure ‎distribution, recirculation zones and drag experienced by the model. These compared parameters helped ‎us to identify whether the mentioned combination is favorable and augments the flameholder ‎performance‎‎.
