In this study， the steady laminar flamelet model is used to describe turbulence-flame interaction， which realizes the decoupling between the flow and the chemical reaction， is able to predict a variety of combustion phenomena well with less computational effort， and proves suitable for application in engineering. The free element method， which only requires a certain number of points to be arranged in the computational area for discretizing the control equations， is employed to overcome the difficulty of complex geometry in engineering. Numerical simulations of laminar counterflow non-premixed flames， two-dimensional axisymmetric co-flow non-premixed methane-air laminar flame， turbulent counterflow non-premixed flame， and burner turbulent non-premixed flame are conducted， respectively. The computational results are studied in comparison with the references to verify the correctness and effectiveness of the free element method in modeling the turbulent combustion.
