Analytical-numerical solution for turbulent jet diffusion flames of hydrogen

摘要: The hydrogen fuel seems to be a good candidate replace the energy obtained from some fossil fuels. Therefore this work explains process of obtaining two-step reduced chemical kinetic mechanism for combustion. development consists in eliminating reactions that produce negligible influence on combustion process. Moreover, mechanism, we obtain an analytical-numerical solution turbulent jet diffusion flame. To quantify intermediate species, mixture fraction is decomposed into three parts, each part directly related mass species. governing equations are discretized using second order finite-difference approach and integrated time simplified three-step Runge-Kutta scheme. Obtained results compare favorably with data literature 50/50 % volume H2−N2 main advantage strategy decrease needed solve system equations, by one magnitude hydrogen.
