Effect of the air-fuel ratio on the emission reduction of a double swirler gas turbine
In this project, the effects of the air-fuel ratio f on the combustion features and emission of a dual swirler combustor have been studied. The fuel is methane that mixed with air that produces O2, CO2, H2O, N2, NO2, CO, and H2. This is a real-world dual-fuel combustor. Grid generation for this complex geometry is done using Gambit and Ansys Fluent is used to do simulations. Turbulent flow is modelled using a k-epsilon method. Certain attention should be paid to capturing turbulence boundary layers consistency with the k-epsilon method to satisfy the required y+ condition in this method. The species transport model with a one-step reaction mechanism is utilized.
