摘要：
In order to develop a prediction and analysis method of thermoacoustic instability for combustor, one can test rig of high temperature rise combustor was secleted as research object,and the low order thermoacoustic network(LOTAN)model of test system was constructed. Based on the experimental data,the parameters of flame transfer function(FTF)under various working conditions were obtained by optimization method, and the response model of gain and hysteresis time to working conditions parameters is fitted by Kriging model. The effects of fuel-air ratio(FAR)and intake speed on the thermoacoustic stability of the combustion chamber were analyzed by using the fitted FTF response model. The results show that the optimized FTF can accurately reflect the unsteady heat release characteristics under various working conditions,and the calculated results imported into LOTAN are in good agreement with the experimental results,the maximum error is about 3.32%. The change of FAR can cause the transformation of unstable mode. When the FAR or intake speed increases,the characteristic frequency of the system also increases. © 2024 Journal of Propulsion Technology. All rights reserved.
