Rehabilitation of St-Marc dam: Model studies for the spillways

Marcelo Leite Ribeiro, Sameh Ahmad Kantoush

The Saint-Marc dam, owned by EDF-France is a concrete gravity dam built between 1926 and 1930. It is located near Limoges (France) on the Taurion River and has currently two gated spillways, one 7.50 m wide on the right bank and the other with two passes o ...

Molecular Wiring of Insulators: Charging and Discharging Electrode Materials for High-Energy Lithium-Ion Batteries by Molecular Charge Transport Layers

Shaik Mohammed Zakeeruddin, Nicholas Evans

Self-assembled monolayers (SAMs) of redox-active molecules on mesoscopic substrates exhibit two-dimensional conductivity if their surface coverage exceeds the percolation threshold. Here, we show for the first time that such molecular charge transport laye ...

Hybrid nanocomposite gas-barrier coatings on polymers

Bandeep Singh

Gas barrier coatings based on single or multiple layers of metals, oxides or nitrides are widely used on polymer substrates in applications ranging from food packaging to organic displays and solar cells. These coatings exhibit a residual permeability resu ...

Intermittent motion and sediment transport -- experimental and theoretical insight

Christophe Ancey

We investigate the entrainment, deposition, and motion of coarse spherical particles within a turbulent shallow water stream down a steep slope. This is an idealization of bed-load transport in mountain streams. Earlier investigations have described this k ...

Atmospheric and sub-atmospheric dielectric barrier discharges in helium and nitrogen

Christoph Hollenstein, Alban Sublet

Dielectric barrier discharges (DBDs) are investigated in helium and nitrogen as a function of pressure from 5 to 1000 mbar. Different regimes are observed: glow, Townsend, multi-peak and filamentary, depending on pressure, power and electrode gap. In heliu ...

Catalytic abatement of volatile organic compounds assisted by non-thermal plasma - Part 1. A novel dielectric barrier discharge reactor containing catalytic electrode

Albert Renken, Lioubov Kiwi

A novel catalytic reactor with dielectric barrier discharge (DBD) at atmospheric pressure was developed for the abatement of volatile organic compounds (VOCs). The novelty of DBD reactor is the metallic catalyst serving also as the inner electrode. The cat ...

Catalytic abatement of volatile organic compounds assisted by non-thermal plasma - Part II. Optimized catalytic electrode and operating conditions

Albert Renken, Lioubov Kiwi

Catalytic purification of air containing 250 ppm of toluene assisted by non-thermal plasma was carried out with a novel dielectric barrier discharge (DBD) reactor with an inner electrode made of sintered metal fibers (SMF). The optimization of the reactor ...

Observation of Spontaneous Toroidal Rotation Inversion in Ohmically Heated Tokamak Plasmas

Basil Duval, Antoine Pochelon, Andrea Scarabosio, Alessandro Bortolon

Bulk plasma toroidal rotation is observed to invert spontaneously from counter to cocurrent direction in TCV (Tokamak à Configuration Variable) Ohmically heated discharges, in low confinement mode, without momentum input. The inversion occurs in high curre ...

Characterization of electrical discharge machining plasmas

Antoine Descoeudres

Electrical Discharge Machining (EDM) is a well-known machining technique since more than fifty years. Its principle is to use the eroding effect on the electrodes of successive electric spark discharges created in a dielectric liquid. EDM is nowadays widel ...

Numerical Analysis of Flow Phenomena Related to the Unstable Energy-Discharge Characteristic of a Pump-Turbine in Pump Mode

François Avellan, Olivier Braun

Regions of positive slope in the pressure-discharge characteristics are one of the major concerns in design and operation of centrifugal pumps, as they are limiting the admissible operating range to values above the critical discharge. The industrial pump ...
