A computer code for solving the Reynolds averaged full N avier-Stokes equations has
been developed and applied using sheared H-type grids. The Baldwin-Lomax eddy-viscosity
model is used for turbulence closure. The integration in time is based on an explicit
four-stage Runge-Kutta scheme. Local time stepping, variable coefficient implicit residual
smoothing, and a full multigrid method have been implemented to accelerate steady state
calculations. Comparisons with experimental data show that the code is an accurate viscous
solver and can give very good blade-to-blade predictions for engineering applications
in less than 100 multigrid cycles on the finest mesh.
