A waterpump for a 6L 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 create a high efficiency volute design from the literature [Kabele71]. The model prescribes scroll cross-sectional shapes and areas at eleven different locations around the volute. In the radial direction this volute's spiral lies between Volute A and Volute B. In the axial direction this volute is larger than any of the previous cases. It is curved on both the top and the bottom allowing for excess volume. This provides us with a uniform shape throughout the volute and a much larger volume within than all previous cases. In order to get the most performance for this case, we remove the sudden expansion/contraction to the outlet used in earlier cases and replaced it with a perfectly smooth transition from the volute to the outlet duct.
The point of this case is to determine the performace ceiling of a text-book
high efficiency volute geometry. The inlet housing, impeller, and
outlet duct portions of this case are identical to the Baseline case.
