Swiss-EnergyScope.ch: a Platform to Widely Spread Energy Literacy and Aid Decision-Making

François Maréchal, Daniel Favrat, Stefano Moret, Victor Codina Gironès

We develop an energy calculator within an online teaching platform to aid citizens and decision-makers understanding an energy system. The model, designed in order to be easily adapted to any energy system at national or regional scale, is presented and ap ...

Large Eddy Simulation of Particle Dynamics Inside a Differentially Heated Cavity

Christoph Bosshard

In nuclear safety, most severe accident scenarios lead to the presence of fission products in aerosol form in the closed containment atmosphere. It is important to understand the particle depletion process to estimate the risk of a release of radioactivity ...

Suprathermal ion transport theory and experiments in the SMT

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

Recent advances in the suprathermal ion diagnostic in the basic plasma experiment TORPEX have inspired our comprehensive theoretical study of suprathermal ion transport. TORPEX, an example of a simple magnetized toroidal plasma (SMT), is equipped with a fl ...

Concentration Compactness for critical wave maps

Joachim Krieger

Wave maps are the simplest wave equations taking their values in a Riemannian manifold (M,g). Their Lagrangian is the same as for the scalar equation, the only difference being that lengths are measured with respect to the metric g. By Noether's theorem, s ...

Management of urban energy systems

Mélanie Guittet

In industrialized countries, more than two-thirds of the energy is consumed in urban areas. Hence, energy sobriety calls for special attention to urban planning, especially regarding energy aspects. ...

Contactless energy transfer with Induction for a miniature Car

Contactless energy transfer is very promising in terms of property and handling. In clean rooms contactless energy transfer allows to build moving robots without any bending cable that emits particles with every movement. We want to test one possibility to ...

energy's and amplitudes' positivity (vol 05, 095, 2010)

Riccardo Rattazzi

We correct typos in eq. (2.41) and (2.42) of ref. [1]. This has several repercussions for the equations of section 2.3, but none for the subsequent sections or for the conclusions of the paper ...

Eliminating Turbulence in Spatially Intermittent Flows

Tobias Schneider

Flows through pipes and channels are the most common means to transport fluids in practical applications and equally occur in numerous natural systems. In general, the transfer of fluids is energetically far more efficient if the motion is smooth and lamin ...

Grid Filter Models for the Large Eddy Simulation of Fluid Flows

Marc Anthony David Habisreutinger

In fluid mechanics, turbulence can occur in very simple flow geometries, for Newtonian fluids and without the need for additional flow conditions such as temperature gradients or chemical reactions. In standard cases, intuitive assumptions on the physics o ...

The Effects of Fluid Elasticity on Grid Turbulence

Richard Vonlanthen

Experiments on grid turbulence are reported for pure water and dilute Polyox WSR 301 solutions. A novel passive grid, which consists of a square mesh grid with tethered spheres, has been developed to enhance the turbulence properties. In pure water the new ...
