J. Eng. Gas Turbines Power. October 2022, 144(10): 101005.
Paper No: GTP-22-1088
Published Online: September 1, 2022
...Yuanqi Fang; Gaofeng Wang; Zengyi Lyu In this paper, we experimentally investigate the thermoacoustic instability issue in an annular combustor with 16 oblique-injecting premixed swirling burners. It is demonstrated that there exist three dominant modes in a narrow operating range: a Helmholtz mode...

...Sheng Meng; Man Zhang This study numerically investigates the effect of spray-wall interactions on thermoacoustic instability prediction. The large-eddy simulations (LES)-based flame transfer function (FTF) and the convective time delay methods are used by combining the Helmholtz acoustic solver...
