The investigation of pollutants emission on counterflow diffusion heating system with multi-step reactions modeling using OpenFoam software

It is necessary to study the flame structure from the approach of its temperature, species consumption rate and pollutants emission. In this paper, the combustion of Methane/Air was investigated with the counterflow diffusion flame model using OpenFoam software. In order to model the problem, Multi-step GRI3.0 mechanism in 324 steps and 53 radical species was used. In this solution, the convergence of unsteady states was considered 10-6 for each time step and residual physical parameters. With the maximum error of 21%, it is an acceptable agreement in the comparison between numerical model and experimental data in the similar state. The results show that in this type of heating system, the amount of the production of carbon emissions that are harmful to human's health are almost critical.
