The three-dimensional transonic flow fields of a turbine stage have been analyzed by computational solutions of Navier-Stokes equations employing an implicit finite deference method with high accuracy upwind scheme. Numerical solutions were compared for different approaches to deal with tip clearance flow. Experimental data were also introduced for verifying the computation. The turbine stage model under consideration consists of inlet guide vanes and rotor blades. Two approaches were examined for dealing with the flow through tip clearance. These approaches have been applied to the turbine for a certain flow condition to evaluate the advantages of them. In this paper the numerical approaches are illustrated and discussed, comparing the resultant flow fields as well as over-all characteristics with experimental data.
