Abstract:
To study the influence of GH2/LOX shear coaxial injector structure parameters on combustion efficiency and stability, numerical simulation of combustion flow field of the single-injector combustor was carried out. The influence of indentation depth of LOX injector, thickness at outlet of LOX injector and gas-to-liquid velocity ratio on the combustor characteristics and stability was mainly studied. The results indicate that the above parameters are the important factors to affect the combustor characteristics of GH2/LOX shear coaxial injector. The combustion efficiency increases with the proper increase of injective velocity ratio and indentation depth of LOX injector. The combustion stability increases with proper increase of thickness at outlet of LOX injector.
