Numerical Simulation of a Confined Swirling Flow in a Model Gas Turbine Combustor

The present paper describes a numerical investigation of a confined swirling flow in a model combustion chamber. two turbulence models, the standard k-e model and the reynolds stress model (rsm) are employed for the flow predictions. solutions to the two-dimensional axisymmetric incompressible reynolds-averaged navier-stokes equations have been obtained by the finite-volume method. comparisons of the present numerical predictions with the available experimental data reveal superiority of the rsm over the standard k-e model for prediction of swirling flows. for instance, rsm predicts the central toroidal recirculation zone well, but k-e does not.
