Assessment of reynolds-averaged turbulence models for prediction of the flow and heat transfer in an inlet vane-endwall passage

Assessment of Reynolds-averaged turbulence models for prediction of the flow and heat transfer in an inlet vane-endwall passage is discussed. Predictions of the flow and thermal fields in an inlet vane passage are obtained via solution of the incompressible Reynolds-averaged Navier-Stokes (RANS) equations. For all of the models, the turbulent heat flux was closed using a constant turbulent Prandtl number of 0.9. Flow visualizations from the computations show that in the regions with relatively high cooling effectiveness, fluid temperatures are near that of the secondary air.
