Three-dimensional viscous flow analysis for centrifugal impellers
Abstract
A space-marching Navier-Stokes solver is presented for simulation of three-dimensional viscous flows in centrifugal impellers. The solver employs finite-volume integration procedures for the partially-parabolic equations written in arbitrary curvilinear coordinates. A solution is achieved using a multiple-pass forward-marching iteration scheme. The accuracy of the analysis method is verified using impeller intra-passage laser velocimeter data. The method is demonstrated to predict the secondary and jet/wake flows, characteristic of centrifugal impellers. The results clearly show the importance of accurately modeling the blade tip clearance flow.
