Abstract

The implicit time-marching finite difference formulations of the Euler and Navier-Stokes equations using the upwind TVD scheme for two-dimensional compressible flows are applied to the flow field in supersonic through-flow fans. The results of the present Euler and Navier-Stokes equations are used to investigate the flow field for various geometrical and flow parameters. It is shown that the difference between the Euler calculation and the Navier-Stokes calculation is conspicuous in the region near shock waves or near the trailing-edge of the blades. Prediction of overall performance, however, is not susceptible to the two calculation models since the difference is limited to narrow region and is of small magnitude, unless the separation and reverse flow regions are generated.
