Numerical modelling of premixed gaseous combustion by the boundary-domain integral method

The numerical procedure of combustion modelling by the boundary-domain inte gral method (BDIM) is presented, based on detailed chemical and physical pr ocesses of the premixed gaseous fuel. The boundary element method is employ ed to solve the conservation equations of overall mass, momentum, energy an d mass species. The law of mass action is applied to determine the chemical reaction rates representing the basis of the source terms in the conservat ion equations for mass species. A freely propagating flame including the fo rced ignition of a homogenous hydrogen-air mixture is calculated as an exam ple problem of the numerical simulation of the combustion processes.
