摘要：
The aim of this study is to perform a numerical simulation of a non-premixed turbulent flame of methane-air enriched by hydrogen. The selected axisymmetric configuration is composed of a central injector of methane-hydrogen mixture surrounded by a bluff-body, which is surrounded by a co-axial air jet. The Ansys CFX software is used to solve the equations governing turbulent reactive flow (Navier Stokes averaged in sense of Favre). The Turbulence is modeled using the k-epsilon model. The EDM (Eddy Dissipation model), then the FRC model (Finite Rate Combustion) combined with EDM are used to modeling the combustion phenomena. The results show some concordance with the temperature profile given by experience to a hydrogen rate of 50%. (C) 2017 The Authors. Published by Elsevier Ltd.
