N2 - The transient injection of methane jet into laminar hot gas and the subsequent auto-ignition were studied by large eddy simulation. The large eddy simulation results are consistent with the experimental results, including jet penetration, temperature, mixing fraction and scalar dissipation rate. The large eddy simulation method has been fully verified. Then, the location of auto-ignition was studied. The auto-ignition kernel always appears at the most reactive mixture fraction, and the scalar dissipation rate is lower. At last, the change of temperature, heat release and species with time in the process of auto-ignition were studied, and the auto-ignition process is divided into three stages: (1) mixing of fuel and hot coflow, (2) auto-ignition process, (3) flame reaches a steady state.
