Abstract

Combustion instability is a type of thermo-acoustic oscillation that can be detrimental for combustion system leading to even flame out. This paper deals with the effect of inlet disturbances on the stability of bluff body stabilized flames and identifies the influence of vortex formation at the bluff body as the principle cause for the onset of oscillations in otherwise stable flame. It also points to the fact that the combustion dynamics can be affected by the inlet flow modulation, which can be used to suppress combustion instability through controlled, phase locked perturbations in the incoming flow.
