Abstract

Pelton turbine is often used where water head is extremely high. Efficiency is an important target of a Pelton turbine during the turbine designing process, many facets will be taken into consideration. However, the performance of a turbine is dominated by the flow in it. The simulations of flow details in a Pelton turbine were conducted in the present work and a kind of negative flow that is two jets flow into the same bucket was detected and evaluated. It will affect the efficiency and the torque character of Pelton turbine. After that, several factors were investigated to find ways to improve the flow condition in the turbine which is proved to be effective. The work will contribute to the design of Pelton turbine.
