Inlet C
A waterpump for a 7L deisel engine application has inspired this study. The baseline design fits between the gear cover on the front of the engine and the radiator fan, a rather narrow space.

For this case, we increase the fillet radius from the inlet housing to the impeller annulus.

The point of this case is to see what performace gains can be made by relaxing smoothing the passage from the inlet housing to the impeller. This case does not modify any outer-parameters and fits in the same constrained case as the Baseling Model. The inlet housing, impeller, volute, and outlet duct portions of this case are identical to the Baseline case.

As before, the impeller diameter is 9.4 cm (3.7 in),the blades are 1.2 cm (0.5 in) tall. The inlet housing's fluid volume is 1.8 cm (0.7in) thick with the master inlet offset frm the impeller inlet. The volute is 1.9 cm (.75 in) deep. The thickness of the entire pump is 4.4 cm (1.7inc).
