Electron imaging of gas diffusion electrodes for proton exchange membrane fuel cells
The current energy crisis demands the development of new sustainable energy sources and devices with low environmental impact, including in the field of electrochemical cells. Mass transport limitations can reduce the overall performance of the device by l ...
EPFL2023Multiscale enhancement of refrigerant falling film boiling by combining commercially enhanced tubes with nanostructures
Multiscale surface structures offer the opportunity to combine the heat transfer enhancement provided by microscale structures with the dryout benefits provided by some nanostructures, which is particularly attractive for falling film evaporators, who have ...
Oxford2023Gravity-Independent Oscillate Boiling
Heat transfer in nucleate boiling relies on the detachment and rise of the boiling bubble, in which gravity plays the dominant role. Previous studies showed that in the absence of gravity, the bubble fails to rise, causing the dryout of the heater and sign ...
SPRINGER2019Predicting homogeneous nucleation rate from atomistic simulations
Predictive modelling and quantitative understanding of nucleation is essential for predicting phase transformation processes in nature and precisely controlling material synthesis and processing. Atomistic modeling is a powerful tool for capturing the dyna ...
EPFL2019Three-dimensional phase-field study of grain coarsening and grain shape accommodation in the final stage of liquid-phase sintering
A 3-dimensional phase-field model is implemented to simulate the grain evolution in the final stage of liquid-phase sintering. The model considers a liquid phase and a polycrystalline solid phase. Results for varying ratios of the solid-solid interface ene ...
Elsevier Sci Ltd2017New particle formation in the southern Aegean Sea during the Etesians: Importance for CCN production and cloud droplet number
This study examines how new particle formation (NPF) in the eastern Mediterranean in summer affects CCN (cloud condensation nuclei) concentrations and cloud droplet formation. For this, the concentration and size distribution of submicron aerosol particles ...
Copernicus GmbH2017Innovative low-mass cooling systems for the ALICE ITS Upgrade detector at CERN
The Phase-1 upgrade of the LHC to full design luminosity, planned for 2019 at CERN, requires the modernisation of the experiments around the accelerator. The Inner Tracking System (ITS), the innermost detector at the ALICE experiment, will be upgraded by r ...
EPFL2016Solvation quantities from a COSMO-RS equation of state
This work focuses on the extension of the successful COSMO-RS model of mixtures into an equation-of-state model of fluids and its application for the estimation of solvation/hydration quantities of a variety of chemical substances. These quantities include ...
Elsevier2015Modeling of percolation of globular-equiaxed grains in Al-Cu alloys
Michel Rappaz, Jean-Luc Desbiolles, Christophe Mondoux
A new mesoscopic model able to describe percolation of globular-equiaxed grains, highly relevant for hot tearing formation in castings, has been developed. This model is inspired from the granular model of Sistaninia et al. [1-5] that considers polyhedral ...
Iop Publishing Ltd2015Mesoscopic Modeling and Experimental Investigations of the Last-Stage Solidification of Globular-Equiaxed Grains in Metallic Alloys
Hot tearing is a major defect of solidification processes and welding. It occurs in metallic alloys while they are in the semi-solid state and is caused by a lack of liquid feeding in the mushy zone to compensate solid network openings due to tensile and s ...
