Flow analysis inside a pelton turbine bucket
WebMay 1, 2007 · Abstract Theoretical analysis has been performed to investigate the flow interaction between the jet and the rotating buckets as well as the relative flow in the buckets of Pelton turbines. The detailed calculation of cut-off processes of the jet by the rotating buckets provides the foundation both in evaluating existing layouts of Pelton … WebThe flow leaving the runner bucket will be converted into dispersed water droplets as the fluid leaves contact from the buckets. This way the flow through the Pelton turbine is multiphase in nature in agreement with the …

WebJan 1, 2007 · Abstract The flow friction in the rotating buckets of a Pelton turbine influences the system efficiency in both the direct and indirect ways. The direct influence is determined by the friction, which directly drives or retards the bucket motion and thus determines the power output. The indirect way is determined by the changes of relative …
