Reaction turbines basically Francis turbines and propeller/Kaplan turbines are suitable for
medium and low head hydropower sites. The management of the small hydropower plants is …

Hydropower is the third largest supplier of global electricity generation trailing behind coal
and natural gas. It serves as the backbone of low-carbon electricity generation, supplying …

An LDA technique and phase-averaging analysis were used to study unsteady precessing
flow in a model vortex burner. Detailed measurements were made for Re= 15,000 and S …

Partial flow rate operation of hydroturbines with constant pitch blades causes complex
unstable cavitating flow in the diffuser cone. A particle image velocimetry (PIV) system …

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

This paper describes the failure analysis of bolts used to connect a turbine to the shaft of a
hydroelectric power generator. Three of ten bolts were found broken during a disassembly …

The complex three-dimensional unsteady flow develo** in the draft tube of a Francis
turbine is responsible for pressure fluctuations, which could prevent the whole hydropower …

The swirling flow develo** in Francis turbine draft tube under part load operation leads to
pressure fluctuations usually in the range of 0.2 to 0.4 times the runner rotational frequency …

Due to the increasing share of new renewable energies like wind and solar in the
generation of electricity the need for power regulation and energy storage is becoming of …
