I*am simulating a case where the oxidizer and fuel are supplied with mass fluxes of 400 and 100 microns in width, respectively. I am employing species transport with volumetric reactions to capture both premixed and diffusion flames in the combustion zone. I am using a detailed reaction mechanism with 38 species and 127 reactions.

When using the laminar flow model with FR/No-TCI, the results are somewhat similar to the experimental data and simulation data available in the literature, although the exact flame structure is not replicated (using only a stiff chemistry solver).

However, when using any turbulent model with FR/ED, combustion is not occurring (using a direct source chemistry solver). I need to use turbulent model.

Could you please assist me with this issue?
Thanks
