The objective of this study is to predict numerically the flow effects of two coaxial jets with different swirl numbers (swirl number) on the characteristics of the turbulent diffusion flame. The study focused on the rotation influence of the secondary flow; that is to say, two configurations were processed and compared: co-swirl and counter-swirl. Obviously, the latter showed higher shear than the first. The calculation results were validated by actual measurement (laser anemometry) of the same configuration for two cases: co- and counter-swirl for reactant with combustion. The calculation results focused on the characteristics of the average flow (reactive) and its turbulence for the two cases cited above. Different parameters were presented such as velocities, temperature, turbulent kinetic energy, and mass fractions of species. The obtained results confirm the swirl effects to stabilize the flame.
