Numerical Prediction of Coaxial Flow Diffusion Flames with Radiative Heat Transfer

Abstract

A new numerical method of evaluating radiative heat transfer was incorporated into the framework of the numerical prediction of diffsion flames. The model of radiative heat transfer was based on tihe idea of the heat ray tracing method originally proposed by Hayasaka et al. The present method enables us to evaluate both the radiative heat loss from a flame and the local formation and oxidation rate of soot, which significantly interact with each other. Some predicted results were compared with those of experiments.
