Abstract
A novel damping model to damp acosutic pressures in gas turbine afterburners is proposed for development and validation in this SBIR project. The proposed model will account for as many of the physical phenomena present in the afterburenr as possible which will include grazing, bias, and mean flows, and heat release fluctuations that excite certain pressure modes and potentially cause screech.
