Heat transfer of uncoated and nanostructure coated commercially micro-enhanced refrigeration tubes under pool boiling conditions
The heat transfer performance of commercially produced micro-enhanced tubes with and without a nanocoating was investigated under pool boiling of saturated refrigerant. These multiscale enhancements were on the outside of 19 mm horizontal copper tubes heat ...
Oxford2023Characterisation of detachment in the MAST-U Super-X divertor using multi-wavelength imaging of 2D atomic and molecular emission processes
Basil Duval, Artur Perek, Kevin Henricus Annemarie Verhaegh
In this work, we provide the first 2D spatially resolved description of radiative detachment in MAST-U Super-X L-mode divertor plasmas. The Super-X magnetic configuration was designed to achieve reduced heat- and particle loads at the divertor target compa ...
IOP Publishing Ltd2023Thermal transport beyond Fourier, and beyond Boltzmann
Crystals and glasses exhibit fundamentally different heat conduction mechanisms: the periodicity of crystals allows for the excitation of propagating vibrational waves that carry heat, as first discussed by Peierls in 1929, while in glasses the lack of per ...
EPFL2021A fast-moving Langmuir probe array for the divertor of the Tokamak à Configuration Variable
In next step tokamaks such as ITER and future fusion power plants, wall materials will be subjected to considerably higher heat and particle fluxes than in present-day machines. Maintaining plasma facing components in good condition and simultaneously assu ...
EPFL2021Parallel convection and E × B drifts in the TCV snowflake divertor and their effects on target heat-fluxes
Basil Duval, Holger Reimerdes, Joaquim Loizu Cisquella, Davide Galassi, Cedric Kar-Wai Tsui, Roberto Maurizio, Mirko Wensing
Parallel convection and E × B drifts act together to redistribute heat between the strike-points mechanisms is enhanced near the secondary X-point and is shown to dominate over heat in the low field side snowflake minus (LFS SF−). The cumulative heat conve ...
2021Thermo-hydro-mechanical behavior of energy tunnels
Matthias Timothee Stanislas Wojnarowicz
Subsurface geothermal in combination with Ground Heat Exchanger (GHE) and heat pumps systems had proved over the past decade to be an effective way in space heating and cooling. GHE’s embedded in geostructures such as tunnels has become more and more attra ...
2020Pressure Drop and Convective Heat Transfer in Different SiSiC Structures Fabricated by Indirect Additive Manufacturing
Sophia Haussener, Ehsan Rezaei, Alberto Ortona, Maurizio Barbato
The microstructure of porous materials has a significant effect on their transport properties. Engineered cellular ceramics can be designed to exhibit properties at will, thanks to the advances in additive manufacturing. We investigated the heat and mass t ...

The microstructure of porous materials has a significant effect on their transport properties. Engineered cellular ceramics can be designed to exhibit properties at will, thanks to the advances in additive manufacturing. We investigated the heat and mass t ...
2019Preparation of high-conductivity, high-capacity phase change media capsules with enhanced thermos-chemical stability in thermal energy storage applications
Thermal energy storage using the effects of the latent heat in the solid-liquid phase transformation has found its way into every day applications. Reusable, organic phase change media stabilize low temperatures of parcels, and salt/water tanks act as buff ...
EPFL2019Cfd-Based Correlation For Forced Convection Heat Transfer In Circular Ducts Of Internally Heated Molten Salts
Heat transfer phenomena involving internally heated fluid flows are of particular interest in several industrial applications, in chemical plants as in the nuclear field. This topic is relevant for the development of the Molten Salt Reactors (MSRs) since i ...
