MODELING OF TURBULENT REACTING FLOWS WITH GASEOUS FUELS IN A COMBUSTION-CHAMBER

The object of this study was to develop an efficient mathematical mode l of turbulent, chemically reacting gas-phase flows under two-dimensio nal steady-state conditions. The solution of the Navier-Stokes equatio ns incorporating physical modelling for turbulence, combustion and the rmal radiation was obtained by combining several computer codes previo usly developed. Numerical results for quantities such as temperature, stream function and species mole number distributions within the flow field were obtained. The performance of the model was tested with expe rimental data from the M-2 trials of the IFRF (International Flame Res earch Foundation). The model assumes a perfectly stirred reactor, so i t does not describe the mixing pattern of the reactants. On the other hand, by using complex reaction mechanisms it gives detailed results f or quantities such as pollutant distributions.
