Abstract

Premixed laminar flame of hydrogen-air mixture is numerically simulated using selected chemical reactions of the I^-O: kinetic mechanism and Zeldovich mechanism for nitric oxide formation. Boundary element method is employed to solve the conservation equations of overall mass, momentum, energy and mass species. The law of mass action is applied to determine the chemical reaction rates representing the basis of the source terms in the conservation equations for species mass. Some of the numerical difficulties associated with the coupling of the source terms in convective-diffusive transport equations are discussed. As an example of numerical simulation the burner stabilized flame at low pressure has been calculated. 1 Introduction Combustion of premixed hydrog
