A three-dimensional code for viscous cascade flow prediction has been
developed. The space discretization uses a cell-centered scheme with e
igenvalue scaling to weigh the artificial dissipation terms. Computati
onal efficiency of a four-stage Runge-Kutta scheme is enhanced hy usin
g variable coefficients, implicit residual smoothing, and a full-multi
grid method. The Baldwin-Lomax eddy-viscosity model is used for turbul
ence closure. A zonal, nonperiodic grid is used to minimize mesh disto
rtion in and downstream of the throat region. Applications are present
ed for an annular vane with and without end wall contouring, and for a
large-scale linear cascade. The calculation is validated by comparing
with experiments and by studying grid dependency.
