A Simple Two-Step Reaction Scheme For Soot And CO Prediction In FDS

Kevin McGrattan – NIST

Abstract

A relatively simple two-step combustion model is proposed for predicting soot and CO generation in under-ventilated fire simulations. The scheme consists of two mixing-controlled reaction steps performed in series. Validation calculations are described, ranging from a laminar diffusion flame to fullscale under-ventilated compartment fires.
