摘要: Abstract The objective of this study was to observe low-frequency instabilities caused by heating kerosene under supercritical operating conditions. Gaseous oxygen and liquid were injected using a shear-coaxial injector. Under specific conditions, the fuel system induced an extremely low frequency pressure fluctuation ranging from 9.9 11.4 Hz. When oscillation occurred in system, combustion instability subsequently range 30–200 Hz. To understand effects temperature on instability, dynamic OH* chemiluminescence intensity measured chamber at high speed. Further, reacting spray visualized shadowgraph technique. In experiment, approximate 3.0 MPa employed order attain condition kerosene. time domain converted frequency-domain spectra fast Fourier transform. Analysis measurements confirmed that had influence instability. From visualization data, it also revealed there existed varying amplitude levels flow rate fluctuation. This turn periodic injection similar both frequency.
