Numerical simulation of deck de-icing using energy pile systems

Aymen Achich

Geothermal energy is heat energy generated and stored in the Earth. With the awareness of the society about environmental issues, geothermal power is developing worldwide. It is cost-effective, reliable, sustainable, and environmentally friendly but has hi ...

2018

The combination of multi-stage heat pump cycles with small-scale oil-free turbocompressor technology running on gas bearings could be a promising way to increase performance in domestic and commercial heat pumps. This paper presents a novel two-stage heat ...

Infrared measurements of the heat flux spreading under variable divertor geometries in TCV

Basil Duval, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Umar Sheikh, Federico Nespoli, Roberto Maurizio

The safe and stable operation of a future fusion reactor depends critically on the ability to control the heat loads on the material surfaces facing the plasma. The heat fluxes are particularly high at the strike points in the divertor, where the plasma in ...

On Using Tunnel Anchors and Bolts as Heat Exchangers with the Ground

Lyesse Laloui, Fabrice Dupray, Thomas Mimouni

Heating and cooling of the buildings represent an important area of energy consumption in the developed countries. Furthermore, a large part of this demand is still satisfied with fossil resources such as oil or gas. Therefore, developing alternative and r ...

2013

Fast ions were analysed in experiments focusing on fundamental He-3 minority and mode conversion (MC) in the ion cyclotron resonance range of frequencies (ICRF) in H plasmas and on second harmonic heating of He-3 ions at 2.65 T mimicking D-T plasma heating ...

2012

The heating and cooling of buildings worldwide represent a large amount of the energy needs and are one of the significant sources of CO2. Decreasing the environmental impact of residential and office buildings is of crucial interest. Energy geostructures ...

Self-Consistent ICRH Distribution Functions and Equilibria in Magnetically Confined Plasmas

Martin Jucker

The deployment of high power radio frequency waves in the ion cyclotron range (ICRF) constitutes an important operational facility in many plasma devices, including ITER. Any charged particle describes a helical motion around a given magnetic field line, t ...

EPFL2010

In magnetically confined fusion devices, the energy and particle transport is significantly larger than expected from purely collisional processes. This degraded confinement mostly results from small-scale turbulence and prevents from reaching self-sustain ...
