COUPLED TURBULENCE, RADIATION, AND SOOT
KINETICS EFFECTS IN STRONGLY RADIATING
NONPREMIXED FLAMES
P. E. DesJardin and S.H. Frankel
A computational study of coupled turbulence, chemistry, and radiation
interactions in an idealized strongly sooting and radiating nonpremixed
turbulent planar jet ame has been conducted. The two-dimensional,
density-weighted, spatially ltered compressible Navier{Stokes, energy
and species equations were numerically integrated using a second-order
time, fourth-order space accurate compact nite-dierence scheme in the
context of the Large-Eddy Simulation (LES) technique. The subgrid-
scale (SGS) stress tensor, scalar ux vectors, and related subgrid corre-
lations were closed using the dynamic Smagorinsky turbulence model.
