Unsteady Flamelet Modeling of Soot Formation in Turbulent Diffusion Flames

摘要

The unsteady flamelet model is applied I a numerical simulation of soot formation in a turbulent C_2H_4 jet diffusion flame. A kinetically based soot model is used, which relies on a detailed kinetic Mechanism to describe the formation of small polycyclic aromatic hydrocarbons. To describe the for- Mation, growth, and oxidation of soot particles, flamelet equations for the statistical moments of the Particle size distribution are derived.
