Numerical prediction of soot formation in combustion chamber for small jet engines

Popis výsledku v původním jazyce

Pollutant formation is monitored in all devices that are used to burn fossil fuels such as burners, engines etc. These pollutants decrease efficiency of burning process and have negative impact on environment. Results of reacting flow field simulation inthe case of combustion chamber for small jet engines will be presented in this paper. Advanced reduced chemical kinetic mechanism is applied in presented simulation. This mechanism allows monitoring of pollutants such as CO, NOx or soot. The suitable model of aircraft common fuel JET A1 should be applied to achieve accurate results. Based on achieved results the new position of nozzle is proposed. This position leads to reduction of pollutant amounts and decease temperature stresses of chamber wall. Developed multi-regional algorithm is used for optimal usage of CPU's and efficient calculations of reacting flow field simulations.
