Hydrodynamics of the free surface flow in Pelton turbine buckets

Alexandre Perrig

The design of Pelton turbines has always been more difficult than that of reaction turbines, and their performances lower. Indeed, the Pelton turbines combine 4 types of flows: (i) confined, steady-state flow in the piping systems and injector, (ii) free w ...

High Speed Flow Visualisation of an Impinging Jet on a Pelton Turbine Bucket

François Avellan, Mohamed Farhat, Alexandre Perrig

This paper deals with flow investigations using endoscopes in a single-injector reduced scale Pelton turbine performed with a CMOS high-speed camera. Both onboard and external visualizations techniques of the flow in a bucket are presented. The flow observ ...

Flow in a Pelton Turbine Bucket: Numerical and Experimental Investigations

François Avellan, Mohamed Farhat, Alexandre Perrig

The aim of the paper is to present the results of investigations conducted on the free surface flow in a Pelton turbine model bucket. Unsteady numerical simulations, based on the two-phase homogeneous model, are performed together with wall pressure measur ...
