Comparative Performance Evaluation of Designed Hooped Pelton Runner with Traditional Pelton Runner

摘要

A new development in Pelton runner design, the hooped runner, is based on a redistribution of functions between the buckets and the hoops, and thus allows stresses to be minimized and distributed more efficiently. This design which combines advantages from the mechanical point of view as well as from the manufacturing aspect without any special drawback from the hydraulic point of view confirms the interest of this new solution. In the present work, the mechanical aspect as well as the results of the hydraulic comparison between traditional runners and hooped runners is made. An actual laboratory scale hoop runner based on this analysis and design is developed and the detailed experimental investigations are also carried out to prove the worthiness of this new design.
