This paper aims to study the effect of a pylon mounted cavity-based flameholder on the combustor performance. Computational analysis of two different models of flame holder 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 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 flame holder performance.

Journal of Applied Fluid Mechanics

The Journal of Applied Fluid Mechanics (JAFM) is an international, peer-reviewed journal which covers a wide range of theoretical, numerical and experimental aspects in fluid mechanics. The emphasis is on the applications in different engineering fields rather than on pure mathematical or physical aspects in fluid mechanics. Although many high quality journals pertaining to different aspects of fluid mechanics presently exist, research in the field is rapidly escalating.
