Combustion of a Spherical Diffusion Flame in a Radiative Field.
Z Zhang, O A. Ezekoye
One methodology for modeling fire induced flow fields is based upon a Lagrangian view of the fire. Large scale processes are modeled using a Large Eddy Simulation (LES) method and are then appropriately coupled to a subgird scale model of the small scale combustion processes. The subgrid scale combustion model utilizes Lagrangian flamelets. On the subgrid scale, detailed computations are performed to calculate the combustion history of an individual fuel element with prescribed initial conditions. In this paper, the soot evolution and burning characteristics within a spherical diffusion flame element are phenomenologically model and the possibility of radiation quenching for certain soot loadings is noted. A comparison is made between finite rate chemistry effects and fast or diffusion limited chemistry results.
