Investigating field-induced magnetic order in Han purple by neutron scattering up to 25.9 T

Frédéric Mila, Bruce Normand, Philippe Heller, Nicolas Laflorencie

BaCuSi2O6 is a quasi-two-dimensional (2D) quantum antiferromagnet containing three different types of stacked, square-lattice bilayer hosting spin-1/2 dimers. Although this compound has been studied extensively over the last two decades, the critical appli ...

Assessment of hydropower potential in wastewater systems and application to Switzerland

Anton Schleiss, Luca Rossi, Pedro Filipe De Almeida Manso, Philippe Heller, Irene Almeida Samora

Energy recovery through local hydropower generation is a way of coping with high electricity expenditures in wastewater systems (WWS). Installing small hydropower plants within WWS is already in some countries eligible for incentive policy mechanisms to re ...

Wave atlas for Swiss lakes: modeling design waves in mountainous lakes.

Azin Amini, Philippe Heller, Blaise Etienne Marceau Dhont

The present study aims to provide a comprehensive wave atlas for Swiss lakes. The atlas is an adequate tool that contains wave characteristics of extreme events derived from numerical calculations. Swiss lakes are surrounded by mountains, and the wind fiel ...

Turbinage des eaux usées, quel potential pour la Suisse?

Anton Schleiss, Luca Rossi, Pedro Filipe De Almeida Manso, Philippe Heller, Irene Almeida Samora

Une évaluation du potentiel de turbinage sur les systèmes d’eaux usées en Suisse a été réalisée au Laboratoire de Constructions Hydrauliques (LCH) en collaboration avec le bureau e-dric.ch. Le potentiel hydroélectrique de chaque STEP a été calculé et compl ...

Reactivation of Klingnau reservoir sidearm: Numerical simulation of sediment release downstream

Anton Schleiss, Giovanni De Cesare, Azin Amini, Philippe Heller

The Klingnau reservoir, situated in north Switzerland, suffers from sedimentation in its left enlargement. The dam is placed in the Aare River about 1 km upstream of its confluence with the Rhine. Due to natural conservation and flood protection reasons, i ...

Comprehensive numerical simulations of sediment transport and flushing of a Peruvian reservoir

Anton Schleiss, Giovanni De Cesare, Azin Amini, Philippe Heller

Numerical modeling of sediment transport in reservoirs, especially for sudden events such as flushing, is still a challenging research topic. In the present study, sediment transport and sediment flushing are simulated for a Peruvian reservoir. Situated in ...

Pumped-storage with small hydropower – an option?

Philippe Heller, Nicolas Crettenand, Benoît Mailler

This paper contributes towards exploring the technical and institutional feasibility of small hydropower storage and pumped-storage schemes in Switzerland. Within the European and Swiss context of the facilitation of renewable energy technologies, which in ...

Comprehensive system analysis of a multipurpose run-of-river power plant with holistic qualitative assessment

Anton Schleiss, Erik Bollaert, Philippe Heller

Alpine rivers have been channelized by significant river training works in the past two centuries and are now disconnected from their natural environment. In adition, their flow regime is often affected by hydropower plant operation. Also the risk of flood ...
