| Abstract: | Numerical simulation of turbulent combustion is performed by using different model combinations. The model combinations are chosen by comparing experimental results. Suitable grid spacings of the numerical system are investigated. Factors influencing on flame length in premixed combustion are discussed, and it is indicated that the influence of air consumption coefficient should be comprehensively considered to control length of flame. |

| Keywords: | turbulent combustion grids density length of flame |
