Abstract
We developed a new design system that enables designing high-performance pumps in a shorter period of time. This system contains a digital engineering tool, which automatically constructs a new 3D-CAD model of the pump impeller after evaluating the flow path shape. The tool was connected to the 3D-CAD/CAE coupling system and used to reduce the time of the design process. The reliability and effectiveness of this system was tested by using it to design a general-purpose small pump. We found that the analytical work time decreased to 2/5 at the first operation and to 1/6 after the second operation. The system was also connected to optimization software and tested in terms of its contribution to improving pump efficiency with regard to other requirements.
