A numerical study was conducted to determine the effect of pressure on the formation of NOx and soot in an axisymmetric 30° counter rotating axial swirler lean low NOx gas turbine combustor. Combustion conditions of 300 deg K inlet air, 0.4 overall equivalence ratio, and pressure of 1 and 10 bar were used. The pollutants studied include soot and NO for which three more additional transport equations such as averaged soot mass fraction, averaged soot particle number density, and averaged NO mass fraction are required. Molecular oxygen was used to model soot oxidation. It was observed that pressure have a major effect on soot formation.
