摘要

The objectives of the present paper is to describe a numerical procedure for the computation of steady turbulent diffusion flames with radiation and its applications to furnaces computations. A n-flux model together with a soot production model is used for radiation. The combustion model, based upon full equilibrium chemistry with an assumed shape mixing rate Probability density function, permits to predicts intermediate species. The standard k-ε model is used for turbulence. The solution procedure uses finite difference methods in 2D, with a characteristics method for advection, in order to minimize numerical diffusion and a "local time step" technique in order to rapidly reach the steady state. A particular treatment of solid boundaries not parallel to coordinates axis makes it possible to map relatively complex geometries.
