Prediction of soot formation and decomposition together with flow-pattern and chemical reactions in turbulent diffusion sooting flame have become very important in recent years. The rate of chemical reactions are determined by the eddy-break-up model (k-ε model) . In the present model on soot, it has been assumed that soot is formed from the total hydrocarbon in two stages, where the first stage represents formation of radical nuclei, and the second stage represents soot particle formation from these nuclei (this model has been well studied and improved the method suggested by Tesner et al.), soot decomposition is determined by the model of Magnussen et al.<BR>The predicted results of the profiles of gas species and soot concentrations are in close agreement with the experimental data.
