Transported PDF modeling of turbulent non-premixed jet flames including soot formation

2010 
The paper presents the performance of a sectional soot model applied to a turbulent nonpremixed jet flame. Gas phase chemistry is solved up to the first polycyclic aromatic ring using finite-rate chemistry. For PAH kinetics a sectional model is adopted. Soot formation is described by two equations for the soot mass fraction and soot number density assuming a mono disperse particle size distribution. On the composition level turbulence is closed by a thermo-chemical transported probability density function (PDF) using the IEM model for molecular mixing. Enthalpy is included in the transported PDF taking both radiation from gas phase species and from soot particles into account. Mean species, soot and flow field quantities are compared to experimental data of a non-premixed sooting jet flame. Two non-sooting jet flames are simulated to validate the employed solver in which the main focus is the investigation of dierent mixing models.
