Effect of the inner-surface baffles on the tangential acoustic mode in the cylindrical combustor
Open Physics, 2020 The combustion instability in a propulsion system is a ubiquitous problem. The radial baffles usually installed on the injector faceplate eliminate the combustion instability (acoustic pressure oscillation) in the propulsion system.

Velocity-Feedback Combustion Oscillation
Bulletin of JSME, 1966 The low-frequency combustion, oscillation occurring in the combustion system comprising a combustion duct, inlet and outlet orifices and a capacity chamber was analyzed as a dynamic instability of "closed loop". From the analysis of experimental facts it was concluded that the exhaust temperature fluctuation as the result of distortion and necking of ...

The bluff body stabilized premixed flame in an acoustically resonating tube: combustion CFD and measured pressure field [PDF]
, 2009 The resulting limit cycle amplitude and frequency spectrum of a flame placed in a combustor of rectangular cross section is investigated. The partially premixed flame is stabilized on a bluff body placed in the upstream half of the combustor.
