Energy production with a tubular propeller turbine

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Cécile Münch-Alligné, Vlad Hasmatuchi, Irene Almeida Samora

Micro-hydropower is a way of improving the energetic efficiency of existent water systems. In the particular case of drinking water systems, several studies have showed that pressure reducing valves can be by-passed with turbines in order to recover the di ...

Simulated Annealing in Optimization of Energy Production in a Water Supply Network

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Irene Almeida Samora

In water supply systems, the potential exists for micro-hydropower that uses the pressure excess in the networks to produce electricity. However, because urban drinking water networks are complex systems in which flows and pressure vary constantly, identif ...

RANS computations for identification of 1-D cavitation model parameters: application to full load cavitation vortex rope

François Avellan, Christophe Nicolet, Andres Müller, Sébastien Alligné

Due to the massive penetration of alternative renewable energies, hydropower is a key energy conversion technology for stabilizing the electrical power network by using hydraulic machines at off design operating conditions. At full load, the axisymmetric c ...

LDV survey of cavitation and resonance effect on the precessing vortex rope dynamics in the draft tube of Francis turbines

François Avellan, Christian Landry, Arthur Tristan Favrel, Keita Yamamoto

The large-scale penetration of the electrical grid by intermittent renewable energy sources requires a continuous operating range extension of hydropower plants. This causes the formation of unfavourable flow patterns in the draft tube of turbines and pump ...

Optimization of low-head hydropower recovery in water supply networks

Irene Almeida Samora

Small scale hydropower is emerging as a decentralized source to satisfy local demand for electricity. The interest in micro-hydropower, which refers to installed power below 100 kW, is increasing since this is a solution with low environmental impact. Wate ...

Assessment of Power Swings in Hydropower Plants through High-Order Modelling and Eigenanalysis

Basile Kawkabani, Pedro Camilo de Oliveira e Silva

Power plants are subject to introduce disturbances in the power grid, resulting from interactions with the dynamical behavior of the energy source subsystem. In the case of hydropower plants when used to compensate for variations of power generation and co ...

Engineering & Performance of DuoTurbo: Microturbine with Counter-Rotating Runners

François Avellan, Vlad Hasmatuchi, Loïc Andolfatto, Daniel Biner

Considering the nuclear phase-out strategy of several European countries and the future tendency to promote renewable energies, the exploitation of small hydropower sites (

Improving Scalability of Symbolic Execution for Software with Complex Environment Interfaces

Stefan Bucur

Manual software testing is laborious and prone to human error. Yet, among practitioners, it is the most popular method for quality assurance. Automating the test case generation promises better effectiveness, especially for exposing corner-case bugs. Symbo ...
