Numerical model for turbulent reactive flows with swirl

This paper presents a numerical method for the computation of turbulent reactive flows. In the present case the combustion is not stabilized by usual flame-holders behind which a recirculation takes place but by a swirler ring which gives a tangential velocity to the flow. Despite the existence of three velocity components, the flow is considered axisymmetric since it depends only on two space variables. In the first part, some points concerning the spatial discretization, the time integration and the ignition process are discussed. In a second part, some numerical results are displayed. The influence of some inlet parameters (stagnation pressure, tangential velocity) is investigated.
