Two-Dimensional Large Eddy Simulation of soot Formation in the Near-Field of a Strongly Radiating Nonpremixed Acetylene-Air Turbulent jet Flame

摘要

A numerical study of soot formation in the near-field of a strongly radiating, nonpremixed, acetylene-air planar jet flame is conducted using Large Eddy Simulation in two dimensions to examine coupled turbulence, soot chemistry, and radiation effects. The two-dimensional, Favre-filetered, compressible Navier-Stokes, total sensitble energy and mixture fraction equations are closed using the Smagorinsky subgrid-scale (SGS) turbulence model.
