This work is devoted to the comparative study for the formation and dissociation of nitrogen oxides by the numerical simulation of turbulent combustion without premix in a combustion chamber having a cylindrical shape with two coaxial jets, two flames using the ANSYS fluent software16.0. The study focuses on the influence of the type of fuel on the composition of discharges in content with NOx, that is to say two cases are treated and compared. Turbulence is modeled by the k-ε model and the chemical aspect of combustion is treated by the PDF model for each flame. The calculation results relate to the characteristics of dynamic fields, temperature, the mass fractions of different species involved in the combustion process and the NOx prediction. The effect of the swirl is also tested in this study with a CFD prediction of non premixed swirling g flame. These results are compared with measurements and confrontations is satisfactory.

“…Kumar et al [7] discussed rotational oscillations and chemical reaction in nonlinear radiative flow. The MHD flow of nanofluid saturating a porous medium is reported by Kumar et al [8]. Few more attempts in this direction have been quoted through the studies [9][10][11][12][13][14][15][16][17][18][19][20].…”

This article reports the magnetohydrodynamic flow of second-grade nanofluid induced by a nonlinear stretching surface with deforming thickness. Darcy-Forchheimer is accounted to characterize the impact of the porous medium. Influences of thermal radiation, nonuniform heat generation/absorption and double stratification process are explored for temperature and concentration distributions. Heat and mass transfer are investigated under the influence Brownian motion and thermophoresis effects. Second-grade nanofluid is electrified under the influence of nonuniform applied magnetic field with small magnetic Reynolds number. Nonlinear partial differential equations are first converted into ordinary differential equations. The outcomes are obtained by the optimal homotopy analysis method. The impact of various physical variables that appear in velocity, temperature and concentration are sketched and discussed. Power index, second-grade variable, Darcy number and Hartman number improve the magnitude of skin friction. Thermal stratified variable enhances the heat transfer rate, while a reverse trend is noted in case of radiation. Brownian motion, solutal stratified variable and Schmidt number lower the Sherwood number.

The bi‐dimensional flow of a Fe3O4‐water nanofluid perfusing a porous medium has been considered for investigation. The porous space is in contact with a constantly heated sheet stretching at a linear rate. To simulate the nanofluid flow through the pores, an extended Darcy model due to Brinkman and Forchheimer is utilized considering porosity and permeability effects in a convective environment. Corcione's model for effective dynamic viscosity of the nanoparticle mixture is exploited to deduce the effects of nanoparticle size on the flow. Multiple solutions to governing equations are obtained by availing the optimal homotopy asymptotic scheme and discussed for emerging parameters. A unique stable solution is determined availing a stability analysis approach. The heat movement rate is found to be increasing with the reduced nanoparticle size and the enhanced porosity of porous space.
