Low-Order Modeling of Low-Frequency Combustion Instabilities in AeroEngines
Rumble is a combustion-induced instability occurring in aeroengines during start-up. Characteristically, low-limit-cycle frequencies between 50 and 150 Hz are obtained. Two basic feedback mechanisms are susceptible to promote rumble: entropy waves being reflected as pressure waves at the (nearly) ch...
