Numerical modeling of nitrogen oxide formation in turbulent combustion of a premixed gas mixture

Based on the particle equilibrium approximation and introducing a prespecified probability density function of the bimodal type, we have developed a method for calculation of the rate of NO formation in turbulent combustion of a premixed gas mixture, taking into account the pulsations in temperature and composition caused by the chaotic motion of the thin reaction zone, the superequilibrium concentration of oxygen atoms, and the energy losses to radiation. Based on the numerical results, we have compared the effects of the listed factors on the rate of nitrogen oxide formation.
