Improved Waste Heat Management and Energy Integration in an Aluminum Annealing Continuous Furnace Using a Machine Learning Approach
François Maréchal, Daniel Alexander Florez Orrego, Réginald Germanier, Manuele Gatti, Mohammad Andayesh
Annealing furnaces are critical for achieving the desired material properties in the production of high-quality aluminum products. In addition, energy efficiency has become more and more important in industrial processes due to increasing decarbonization r ...
2023Bistable Puncturing Tool for Retinal Vein Cannulation
Yves Bellouard, Simon Nessim Henein, Charles Baur, Lisa Anaïs Jeanne Bonnefoy
An innovative surgical tool prototype dedicated to safe puncturing has been developed for the treatment of retinal vein occlusions (RVOs). The tool is manufactured monolithically by femtolaser printing in fused silica. It consists of a programmable bistabl ...
2020Review on ventilation rates in the ventilated air-spaces behind common wall assemblies with external cladding
Dolaana Khovalyg, Mohammad Rahiminejad
For many decades, ventilated cavities in wall assemblies of buildings have been essential for creating moisture resilient constructions by allowing airflow within the air gap to promote drying. In addition to that, the airflow in the cavity can enhance the ...
2020Nanosecond pulsed laser-processing of CVD diamond
Patrik Willi Hoffmann, Marco Cantoni, Sébastien Equis
This work considers the resulting material structural effects of laser-processing chemical vapor deposited (CVD) diamond. The utilized 532 nm wavelength laser had a pulse duration of 40 ns together with a spot diameter of ca. 40 mu m. The effect of cutting ...
ELSEVIER SCI LTD2020The ratio of shear to elastic modulus of in-plane loaded masonry
Katrin Beyer, Bastian Valentin Wilding, Michele Godio
When designing unreinforced masonry buildings, the wall stiffness and, consequently, the masonry elastic and shear modulus E and G are essential parameters. Current codes provide empirical estimates of the masonry elastic modulus and a ratio between the sh ...
2020Power-to-methane via co-electrolysis of H2O and CO2: The effects of pressurized operation and internal methanation
François Maréchal, Jan Van Herle, Stefan Diethelm, Ligang Wang, Tzu-En Lin, Hanfei Zhang
This paper presents a model-based investigation to handle the fundamental issues for the design of co-electrolysis based power-to-methane at the levels of both the stack and system: the role of CO2 in co-electrolysis, the benefits of employing pressurized ...
2019Power-to-fuels via solid-oxide electrolyzer: Operating window and techno-economics
François Maréchal, Jan Van Herle, Stefan Diethelm, Ligang Wang, Tzu-En Lin
Power-to-fuel systems via solid-oxide electrolysis are promising for storing excess renewable electricity by efficient electrolysis of steam (or co-electrolysis of steam and CO2) into hydrogen (or syngas), which can be further converted into synthetic fuel ...
2019New approach to low thermal conductivity of thermal barrier protection with improved mechanical integrity
Heinrich Hofmann, Paul Bowen, Abhishek Tewari
Layered ceramic systems with designed stacks of dense and porous layers were investigated as alternative for thermal barrier protection system (TBPs). This approach gives the possibility to obtain low thermal conductivity with the impact protection of dens ...
Elsevier2016Progressive activation of degradation processes in solid oxide fuel cells stacks: Part I: Lifetime extension by optimisation of the operating conditions
Daniel Favrat, Jan Van Herle, Arata Nakajo
The degradation of solid oxide fuel cells (SOFC) depends on stack and system design and operation. A methodology to evaluate synergistically these aspects to achieve the lowest production cost of electricity has not yet been developed. A repeating unit mod ...
Elsevier2012Cloud formation in the plumes of solar chimney power generation facilities: A modeling study
The solar chimney power facility has the potential to become a valuable technology for renewable energy production. Its financial viability depends on a thorough understanding of the processes affecting its performance, particularly because of the large st ...
