ABSTRACT: The paper numerical studied the MILD(Moderate or Intense Low-oxygen Dilution) combustion mode and performances in the designed gas turbine chamber. The influence of air jet Re number on flue gas recycles ratio Kv and hereby on kerosene fuel MILD combustion were modeled. For fixed equivalence ratio, increasing the air jet Re number to the Kv value of 3.3 - 3.8, MILD combustion mode will be formed. It has MILD combustion performances of volume combustion, excellent outlet temperature field and very low pollutant emissions. Combustor confinement has little effects on MILD combustion. Calculating results agree with other’s similar experimental data.
