Fuel reverse injection has changed the traditional aero-engine combustion methods of fuel injection at combustor head and swirl combustion stability, which utilizes high temperature and lowers oxygen content conditions within flue gas recirculation zone to achieve MILD combustion mode of stabilization, high efficiency and ultra-low pollute emissions.This paper simulated and analyzed the effects on MILD combustion mode and combustion performances by changing the nozzle locations and angles of reverse injection.When the combustion parameters of nozzle location and angle are appropriate, MILD combustion mode based on the inlet air temperature and excellent combustion performances of high quality outlet temperature fields, ultra-low NOx emission can be achieved.All results correspond to other similar findings and have reference values to new concept aeroengine design.
