Innovative thermophysical characterization of an ATF composite cladding: the case of silicon carbide
Nuclear power is a powerful technology that plays an important role in the fight against climate change, and research is continuously engaged in studies that could further improve its safety. After the Fukushima accident, Accident Tolerant Fuels research h ...
EPFL2024Unearthing 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 Soc2024Experimental study of the hydrodynamic and thermal performances of ventilated wall structures
Dolaana Khovalyg, Mohammad Rahiminejad
The presence of a ventilated air gap behind the external cladding in a building envelope is known to have a tangible contribution to the overall performance of the wall assembly. In the present study, the hydrodynamic and thermal performances of ventilated ...
2023Conductive Heat Transfer in Partially Saturated Gas Diffusion Layers with Evaporative Cooling
Sophia Haussener, Felix N. Büchi, Mirco Magnini
Heat transport is an important, though often neglected function of gas diffusion layers (GDLs) of polymer electrolyte membrane fuel cells. Thermal conductivity is a key property, especially in partially water saturated GDLs and when the phase change of wat ...
2022Many-body Green?s function approach to lattice thermal transport
Nicola Marzari, Michele Simoncelli
Recent progress in understanding thermal transport in complex crystals has highlighted the prominent role of heat conduction mediated by interband tunneling processes, which emerge between overlapping phonon bands (i.e., with energy differences smaller tha ...
AMER PHYSICAL SOC2022Thermal 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 ...
EPFL2021Impact of air-flow on thermal performance of air-spaces behind cladding (ASHRAE 1759-TRP)
Dolaana Khovalyg, Mohammad Rahiminejad
The project ASHRAE 1759-RP addresses the impact of the ventilated cavity behind external claddings on the thermal performance of the wall structure by defining “effective thermal resistance” of air gaps based on the linearized network of thermal resistance ...
ASHRAE2020Effective conductivity of porous ceramics in a radiative environment
Sophia Haussener, Clemens Gregor Suter, Jérémy Raphaël Mora-Monteros
The knowledge of the effective thermal conductivity, taking into account conduction and radiation, is crucial for the accurate prediction of the thermal behavior of porous foams, especially in an environment where radiation is dominating. We present a comb ...
2019Modeling and experimentation of conductive and radiative transfer through heterogeneous insulators in high-flux environments
Heterogeneous materials are used in a wide range of applications involving high heat flux environments such as concentrated solar reactors, high-temperature furnaces, or thermal protection systems of space vehicles. The thermal response of heterogeneous ma ...
