In this paper the results of experimental and numerical investigations of swirl burner were presented. Mathematical model for prediction of velocity, temperature and concentration fields of axisymmetrical confined swirl turbulent flame was developed. Model consists of few mutually coupled segments related to basic processes in turbulent flows with combustion. The original combustion rate model based on the ideal reacting hypothesis within fine structure of turbulence was applied. The comparison of the experimental results with computation showed satisfactorily agreement between the model and the experiment. This analysis also showed the importance of the proposed combustion rate model with simultaneous influence of both chemical kinetics and turbulent effects. (c) 2005 Elsevier Ltd. All rights reserved.
