| Summary: | The effects of chamfering and corner radiusing on the discharge coefficient of rotating axial orifices are presented in this paper. Both experimental and CFD results show that chamfering and corner radiusing improve the discharge coefficient of rotating orifices. For non-inclined rotating orifices, the discharge coefficient reduces with increasing speed, but chamfered and radiused orifices manage to have higher discharge coefficient (Cd) than the straight edge orifices. Comparing between chamfering and corner radiusing, the radiused corner orifice has the highest Cd at every rotational speed. This is because the inlet radius helps guiding the flow into the orifice and avoiding flow separation at the inlet. � Published under licence by IOP Publishing Ltd. |
