NAVIER-STOKES SOLUTION FOR STEADY TWO-DIMENSIONAL TRANSONIC CASCADE FLOWS.

A robust, time-marching Navier-Stokes solution procedure based on the explicit hopscotch method is presented for solution of steady, two-dimensional, transonic turbine cascade flows. The method is applied to the strong conservation form of the unsteady Navier-Stokes equations written in arbitrary curvilinear coordinates. Cascade flow solutions are obtained on an orthogonal, body-conforming double prime O double prime grid with the standard k- epsilon turbulence model. Computed results are presented and compared with experimental data.
