In this simulation, we have performed a combustion simulation on the combustor model and plotted the variation of the mass fraction of the different species in the simulation using line probes at different locations of the combustor. Plots for CO2, H2O, CH4, N2, O2, NOx emissions & Soot formation have been attached.…
