Abstract:
Soot formation in a methane turbulent diffusion flame is simulated. Combustion is treated using steady flamelet model and a detailed chemistry. Turbulence is taken into account by k-ε model, with a round jet correction. Radiation heat transfer from flame is modeled by the P- 1 model. Soot distribution in the chamber is described by two parameters, i.e. soot number density and soot mass fraction. Two transport equations are solved for soot number density and soot mass fraction. Rates of soot particle nucleation and coagulation are included in the source term of soot number density equation, while soot particle nucleation, particle surface growth and soot oxidation contribute to the source term of soot mass fraction equation. Radial and axial profiles of temperature, species and soot distribution are generated and compared with experimental measurements. There is a good agreement between results of numerical simulation and experimental measurements. Radiation heat transfer from gas phase showed to have a considerable effect on both temperature field and soot formation profiles.
