AB - <p>The demand for new sources of alternative fuels, to replace the use of fossil fuels and reduce gas emissions, hasincreased in recent years. Hydrogen has increasingly become an interesting alternative fuel as it does not producegreenhouse gas CO2and can increase fuel economy when used in hydrocarbon mixtures. In this work, a numericalsimulation was carried out for diffusion flames of hydrogen inside a rectangular burner. Therefore, Navier-Stokesreactive equations were applied, mixture fraction for the flow and for the chemical part the flamelet method. Forthe modeling of turbulence, the known technique was used as large-eddy simulation (LES), and the finite differencemethod to discretize the equations. Simplifications were also carried out in terms of the equations to reduce thecomplexity of the problem. The numerical results obtained were compared with data found in the literature.</p>
