Abstract
A method for predicting flow in diffusers with inlet swirl has been de veloped. Solutions of the pressure flux-split reduced Navier-Stokes eq uations are obtained for flows in axisymmetric diffusers. Viscous-invi scid interactions and flow fields with toroidal recirculation regions are efficiently captured. The computational model is verified by compa rison with experimental data and other computations. The extreme sensi tivity to grid, turbulent closure model and inlet profiles is discusse d.
