The assessment of existing infrastructures in the energy sector is great economic importance for world. extension power generation life hydroelectric plants depends on logical decisions regarding maintenance and renewal equipment. For this purpose, a Bayesian network (BN) has been applied to evaluate failures hydraulic turbine calculate failure turbine. Forty-six nodes have identified that will...

In this paper, the Eulerian–Lagrangian method and Tabakoff erosion model are used to study solid–liquid two-phase flow in a Francis turbine. Through analysis of overall pattern, particle flow, concentration, wear bladeless area unit under different guide vane openings, influence runner radial gap on surrounding field characteristics openings is revealed. The results show that smaller opening va...

A range of continental-scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions (PTFs) for applications principally on spatial datasets with continental coverage. The PTF development included the prediction of soil water retention at various matric potentials and prediction of parameters to ch...

Hydroelectric power plants are environmental-friendly as they renewable energy sources and make great contributions to the economies. In addition, in state of insurance electricity network, since can respond demands network a very short time. this study, effect speed governors dispense valve has been added classical control mechanism order accurately predict reaction hydroelectric load requirem...

ABSTRACTRenewable Energy Sources (RES) are well – defined as energy sources, that are in abundance within the natural surroundings and are much inexhaustible. In addition, hydroelectricity (HE) is a vital part of world renewable energy supply and hydropower remains a bulk source of electricity generation because of its environmental friendliness in nature. Modeling is the analysis of the ...
