Granular dynamics in a swirled annulus
WebJan 1, 2005 · Swirling flows may affect flame dynamics in two aspects. First, large-scale unsteady motions arising from shear-layer instability and vortex breakdown, as well as precession of vortex core (PVC), may couple resonantly with acoustic waves in the combustor, and subsequently cause combustion instabilities.

WebSep 1, 2024 · Ahn et al. [24] studied the effect of recess length on the mixing and combustion dynamics in a combustor with 19 bi-swirl injectors over a pressure range of 4.2-5.4 MPa. For each injector, liquid oxygen (LOX) and kerosene were injected tangentially into the center tube and coaxial outer annulus, respectively. WebSep 21, 2024 · The ignition sequence during light-around (order in which the injectors are ignited) was found to be highly repeatable, igniting each consecutive injector in the anticlockwise direction (the direction of bulk swirl). In rare cases, the ignition sequence was observed to branch in both directions.
