Together with the world economic growth is the increasing of energy generation demand. However, the upgrade of world power production capability could affect the environment negatively. Even the clean and renewable sources, such as hydroelectricity a
The paper presents a numerical analysis of flow in a 6-jet Pelton turbine for 1-nozzle operation. Flow in the manifold with injectors was analysed in order to get inlet conditions for runner analysis, which was at first performed without cavitation.

This paper presents results of the numerical analysis of two Pelton turbines: a 6-jet turbine for middle head and a 2- jet turbine for high head. For the 6-jet turbine losses in manifold, quality of the jets and turbine efficiency were predicted and

Compte tenu de l'importance de maintenir une qualité optimale des cordons de soudure et l'impossibilité d'assurer tout risque de manque de pénétration et de fusion par des contrôles non-destructifs, cette thèse permettra de développer une expe
