“…3) an independence of the solution from 1950000 nodes. The variation of nodes number shows dierences of the maximum temperature achieved and its evolution along the axis X, however, the position of the ame front from the nozzle burner at X = 0.025 m was not aected where all mesh cases studied oered a similar solution found by experimental data [13].…”

“…Numerical LES of LSB [4] burner for turbulent premixed methaneair ames and published a study where they changed the calculation source term in the G-equation combustion model and compared it with the C-equation model and his own experiences is proposed in Ref.

This work presents a numerical simulation of premixed methaneair low swirl stabilized ame, the geometry describes a low swirl burner kind. Reynolds average NavierStokes standard κ−ε model for turbulence coupling to partially premixed model for combustion were used with varying methane equivalence ratio from 0.6 to 1.4. Parameters governing ame structure are investigated; velocity, temperature, CH4 distribution and thermal nitric oxide apparitions elds, results are compared and validated with experimental and large eddy simulation works cited in references, they oer good similarities for all ame parameters studied. Actual study works to nd equilibrium between the maximum of generated temperature and the minimum of thermal NO pollutant emissions for low swirl burners without neglecting the ame stabilization which must be maintained.
