Hydropower is a clean and renewable source of energy which is widely used to generate
electric power and stabilize the power grid. It can respond quickly to any change in demand …

Additive manufacturing (AM) has unique capabilities when compared to traditional
manufacturing, such as shape, hierarchical, functional, and material complexity, a fact that …

An experimental and theoretical investigation of the flow at the outlet of a Francis turbine
runner is carried out in order to elucidate the causes of a sudden drop in the draft tube …

Francis turbine working at off-design operating condition experiences high swirling flow at
the runner outlet. In the present study, a high head model Francis turbine was …

Abstract Rotating Vortex Rope (RVR) resulting from flow instabilities inside draft tube affects
the hydraulic turbine's efficiency and wear. Among the passive and active RVR mitigation …

Abstract Rotating Vortex Rope (RVR) has been a matter of focus for years due to the major
effects on hydraulic turbine's efficiency. The exact procedure of RVR formation is still vague …

The penetration of intermittent wind and solar power to the grid network above manageable
limits disrupts electrical power grids. Consequently, hydraulic turbines synchronized to the …

Applications of computational fluid dynamic (CFD) techniques to hydropower have
increased rapidly in the last three decades. The majority of the experimental investigations …

Hydropower refers to energy conversion from flowing water into electricity. Due to water
recycling by the Sun, hydropower is widely accepted as a form of renewable energy. A …
