Flow measurements in sewer systems based on image analysis: automatic flow velocity algorithm

David Andrew Barry, Luca Rossi, Daniel Sage, Laurent Son Nguyen, Salim Kayal, David Jeanbourquin

Discharges of combined sewer overflows (CSOs) and stormwater are recognized as an important source of environmental contamination. However, the harsh sewer environment and particular hydraulic conditions during rain events reduce the reliability of traditi ...

Unstable Operation of Francis Pump-Turbine at runaway: Rigid and Elastic Water Column Oscillation Modes

François Avellan, Jean-Jacques Simond, Basile Kawkabani, Sébastien Alligné

This paper presents a numerical simulation study of the transient behavior of a 2x340MW pump-turbine power plant, where the results show an unstable behavior at runaway. First, the modeling of hydraulic components based on equivalent schemes is presented. ...

Influence of the Francis turbine location under vortex rope excitation on the hydraulic system stability

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Philippe Allenbach, Basile Kawkabani, Sébastien Alligné

Hydroelectric power plants are known for their ability to cover variations of the consumption in electrical power networks. In order to follow this changing demand, hydraulic machines are subject to off-design operation. In that case, the swirling flow lea ...

ACOUSTIC RESONNANCE IN CAVITATION FREE AND CAVITATING FLOWS

François Avellan, Sébastien Alligné, Nicolas Ruchonnet

At part load operation of Francis turbine, the swirl in the draft tube leads to flow instability known as vortex breakdown. This flow instability can interact with the rest of the hydraulic circuit through axially propagating plane-waves. Moreover, at low ...

Vortex shedding from blunt and oblique trailing edge hydrofoils

François Avellan, Mohamed Farhat, Philippe Ausoni, Amirreza Zobeiri

The phenomenon of vortex shedding behind a hydrofoil is an important issue from both scientific and technical point of view. The resulting fluctuating forces may lead to excessive vibrations and premature cracks in the hydraulic machines. According to prev ...
