Abstract

A composition PDF methodfor gas-phase thermochemistry is coupled with a method of moments for soot particle dynamics. The resulting model is used to simulate experimental ethylene/air jet fiame with a jet Reynolds number of 11800. A simplified nucleation mechanism and a modified surface-HACA mechanism for surface growth are used for soot. Gas-phase thermochemistry is modeled using a reduced mechanism for ethylene consisting of 33 species and 205 elementary reactions. The soot formation mechanism is coupled directly with the transported PDF approach to account for turbulence. chemistry interactions in gas phase chemistry and the highly nonlinear soot formation processes. Radiation from soot and combustion gases is accounted for using an optically thin approximation. Simulation results are compared with experimental data.
