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 ...
