Plasmoid drift and first wall heat deposition during ITER H-mode dual-SPIs in JOREK simulations
The heat flux mitigation during the thermal quench (TQ) by the shattered pellet injection (SPI) is one of the major elements of disruption mitigation strategy for ITER. It's efficiency greatly depends on the SPI and the target plasma parameters, and is ult ...
Iop Publishing Ltd2024Computational fluid dynamics simulations of the heat transfer properties of graphene-based nanolubricants and application to hydrodynamic lubrication
In this paper, we consider experimental data available for graphene-based nanolubricants to evaluate their convective heat transfer performance by means of computational fluid dynamics (CFD) simulations. Single-phase models with temperature-dependent prope ...
Aip Publishing2024Decomposition method to evaluate district heating/cooling network potential at urban scale
François Maréchal, Luc Girardin, Ana Catarina Gouveia Braz, Bingqian Liu, Raphaël Briguet
In this work, a tool to design district heating networks (DHN) is presented and applied to the city of Lausanne as a case study. The evaluation of the buildings’ heat/cooling demand is performed using a Geographic Information System (GIS) database, built f ...
Associazione Italiana Di Ingegneria Chimica2024Unearthing the foundational role of anharmonicity in heat transport in glasses
The time-honored Allen -Feldman theory of heat transport in glasses is generally assumed to predict a finite value for the thermal conductivity, even if it neglects the anharmonic broadening of vibrational normal modes. We demonstrate that the harmonic app ...
Amer Physical Soc2024Gyrokinetic turbulence modeling of a high performance scenario in JT-60SA
Stefano Coda, Stephan Brunner, Aylwin Iantchenko
Local gyrokinetic simulations are used to model turbulent transport for the first time in a representative high-performance plasma discharge projected for the new JT-60SA tokamak. The discharge features a double-null separatrix, 41 MW of combined neutral b ...
Bristol2024Thermal conductivity of Li 3 PS 4 solid electrolytes with ab initio accuracy
Michele Ceriotti, Federico Grasselli
The vast amount of computational studies on electrical conduction in solid-state electrolytes is not mirrored by comparable efforts addressing thermal conduction, which has been scarcely investigated despite its relevance to thermal management and (over)he ...
Amer Physical Soc2024Identification and Mitigation of Degradation Mechanisms Induced by Heat and Light in NiOx-based Perovskite Solar Cells
Marion Solange Madeleine Dussouillez
Perovskite solar cells (PSCs) offer an attractive solution to increase the efficiency of PV panels via perovskite/silicon tandems thanks to their potential cost-effectiveness and high efficiency. In inverted PSC architecture (p-i-n), commonly used hole con ...
EPFL2024Beam radiation penetration in particle b e ds for heat transfer modeling of a centrifugal solar particle receiver
Evan Fair Johnson, Serdar Hiçdurmaz
This article describes a study of beam radiation striking particle beds of randomly packed, spherical par-ticles. The current study is focused on concentrating solar power receivers which use solid particles as a heat transfer medium, but results are appli ...
PERGAMON-ELSEVIER SCIENCE LTD2023Fractures Thermal Energy Storage (FTES)
This project aims at designing a laboratory-scale experiment to investigate the thermal performance of Fractures Thermal Energy Storage (FTES) systems. While previous field tests have focused on creating horizontal planar fractures at shallow depths, none ...
2023Heat 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 ...
