The dynamic behavior in combustion instability near lean blowout exhibits a self-affine structure and is ascribed to fractional Brownian motion. It undergoes chaos by the onset of combustion oscillations with slow amplitude modulation. Our results indicate that nonlinear time series analysis is capable of characterizing complexities in combustion instability close to lean blowout., 資料番号: PA1210016000}, pages = {043128-1--043128-8}, title = {Characterization of complexities in combustion instability in a lean premixed gas turbine model combustor}, volume = {22}, year = {2012} }
