We present a numerical simulation of a CH4/air reacting coaxial jet confined in a cylindrical combustion chamber. This study focuses on non-premixed turbulent flame. The simulation, performed by Fluent software, is based on the coupling between Beta-PDF approach and LES-WALE model subgrid-scale. The numerical validation is confirmed by comparisons of predictions results and reference experimental data, Spadaccini et al. (1976). It showed that a good agreement and reliable statistically predictions against experimental data.
