英文摘要	The experimental data of lean blowout fuel/air ratio of a rectangular swirl cup combustor with different inlet temperatures was obtained at atmospheric pressure condition. Numerical simulations both burning and non-burning were performed corresponding to the experimental data at lean blowout. Results indicated that the size of the recirculation region in the primary zone was obviously smaller when burning than non-burning, but the locations of the cores of their recirculation regions were almost the same. The increase of inlet air temperature didn't mean the rise of the temperature of recirculation region core. The location of the maximum temperature in the primary zone was not the same as that one of the core temperature of the recirculation region. Further more, the reasons were analyzed how the lean blowout fuel/air ratio changed with the inlet temperature increasing under the actions of factors both positive and negative to combustion, and this would be helpful to deepen the understanding of the lean blowout process of swirl cup combustor.
