4 Summary In this paper, incompressible Navier-Stokes solvers designed for three-dimensional flow simulations have been discussed. The discussion has been limited to the primitive-variable formulation as it causes fewer complications in setting the boundary 32 conditions. Numerous computed results have been presented to illustrate the numerical procedures. Even though computer speed and memory have been increased substantially in the recent past, the speed and the memory requirements of a flow solver are still major factors affecting the turnaround time.

The particles tend to flow from the hub to the tip of the blade. The particles near the inducer leading edge and full blade trailing edge indicate the presence of back flow. Fig. 24. Velocity vectors inside various bearing geometries. Parametric studies to eliminate the back flow near the hub region by tapering the hub surface have also performed for this configuration. Figure 22 shows the circumferentially averaged meridional velocity distribution along the blade height for various designs. The original blade design is referred to as Design I.
