Simulation of combustion in porous burner with different mechanisms and compare them

The complexities of solving the combustion problem cause that the time of solving equations becomes too long; therefore, efforts have been made to reduce this time by the appropriate simplifications. In this study, combustion in porous medium is modeled by using the GRI3.0 and Miller kinetics, as well as their corresponding reduced kinetics in different equivalence ratios and the results have been compared in terms of carefully calculated temperature distribution and emission of pollutants as well as the cost and time of using each kinetics. Studies show that the results of reduced kinetics are consistent with the results of full kinetics with a good accuracy; moreover, their convergence time is much less than the full kinetics without dependence on the number of grid points
