Linear Instability Analysis of Lean Premixed Combustion
Journal of Thermal Science and Technology, 2012 Combustion oscillation of a self excited combustion-acoustic phenomenon occurs inside the gas turbine combustor. In general, excessive pressure fluctuation of combustion oscillation may impair the gas turbine engine operation and may result in hardware ...

Journal of the Fuel Society of Japan, 1971 The combustion in propulsion engines or industrial furnaces is never perfectly smooth and is usually accompanied with random fluctuations in the combustion rate as well as in pressure and velocity. When the pressure fluctuation becomes in phase with the fluctuation in the heat release rate of combustion, the fluctuation will develop into the organized ...
