  • Based on the results of numerical simulation, experimental research on the GO2/GCH4 coaxial shear injector was carried out using non-intrusive optical diagnostic techniques, including PLIF(planar laser induced fluorescence), high-speed camera and so on. The OH distribution of combustion chamber, the development of combustion flow field and the flame structure were obtained by measuring the combustion flow field at different operating conditions. The results showed that there were obvious shear combustion layers in the combustion flame of GO2/GCH4. As the axial distance increased, the flame gradually lost its stability. With the increase of the velocity ratio, the vortex of the flow field was obviously strengthened, the flame root stabilization section became shorter and the flame structure had more curl and wrinkles. The simulation of OH distributions is consistent with the measurement of OH distribution, indicating the simulation model can simulate the combustion flow field of GO2/GH4.
