초록·키워드
Water supply networks (WSN) are important structures in urban and industrial environments that are built to transport fluid between several supply and demand points. However, a significant amount of pressure energy still remains at the end of the water supply pipe system. This energy is usually released and wasted. Therefore, a pico propeller turbine was chosen as a solution to recover the energy. In order to study more deeply on the performance of a pico propeller turbine in a laboratory environment, a new runner model was designed to improve the performance of the existing runner model. The design of the new runner blade model considers several key parameters such as the hub-tip diameter ratio and velocity triangle calculation which govern blade performance. The performance of the new runner model was evaluated by CFD analysis and compared with the performance characteristics of the old runner model. The internal flow and cavitation performance were also investigated for the new runner design.
