COMPREHENSIVE MODELING OF TURBULENT FLAMES WITH THE COHERENT FLAME-SHEET MODEL .2. HIGH-MOMENTUM REACTIVE JETS

This paper describes the application of computational fluid dynamics ( CFD) to the prediction of the characteristics of high-momentum vertica l and horizontal flames in ambient airflows. The KIVA-II code has been modified by extending the range of boundary conditions and by the add ition of the following I a version of the coherent flame-sheet model, Tesner's soot generation and Magnussen's soot oxidation model, and an implementation of the discrete transfer radiation model. To assess the accuracy of the complete model for prediction purposes, results are c ompared with experimental data. Predictions of temperature and flame p rofiles are in good agreement with data while predictions of radiative heat transfer are not entirely satisfactory.
