On the physical mechanism of tip vortex cavitation hysteresis
Mohamed Farhat, Matthieu Dreyer, Ali Amini, Martino Reclari
Inception and desinence thresholds of tip vortex cavitation (TVC), generated by an elliptical NACA 16-020 hydrofoil, are measured at different flow conditions for various gas contents. It is observed that TVC often disappears at cavitation indices signific ...
SPRINGER2019Hydrogen sieving from intrinsic defects of benzene-derived single-layer graphene
Kumar Varoon Agrawal, Mostapha Dakhchoune, Shiqi Huang, Jing Zhao, Mina Moradi, Majharul Haque Khan
Single-layer graphene films, crystallized by chemical vapor deposition, host a low density of vacancy defects that are attractive for the size-sieving of molecules. The size and the density of such defects are a function of the growth temperature and the c ...
2019Gaznat se tourne vers l’EPFL
Prof. Laloui discussed some of the major challenges facing CO2 geosequestration, a technology which could be vital in Switzerland’s transition away from nuclear as this may mean increased reliance on natural gas. Many of these challenges, such as cap rock ...
2018Methane oxidation over a honeycomb Pd-only three-way catalyst under static and periodic operation
Natural gas is receiving increasing awareness as fuel for passenger vehicles due to its very low specific CO2 emissions. However, control of CH4 emissions from natural gas combustion in stoichiometric engines requires a specific three-way catalyst (TWC). T ...
Elsevier Science Bv2018Reversible Segregation of Ni in LaFe0.8Ni0.2O3 +/-delta During Coke Removal
The deactivation of supported nickel catalysts by coking is an important technological subject for many chemical processes, especially when high concentrations of unsaturated hydrocarbons are present in the feed gas. Here, the reversible segregation of Ni ...
WILEY-V C H VERLAG GMBH2018Hydro-mechanical analysis of gas transport in compacted bentonite: uncertainty modelling
In the last years, transport of gases in clay buffer materials for Engineered Barrier Systems (EBS) has been deeply investigated by many research programs in the framework of nuclear waste storage. At present state, the coupled hydromechanical models to an ...
TU Delft2018Exergy Recovery During Liquefied Natural Gas Regasification Using Methane as Working Fluid
François Maréchal, Francesco Baldi, Francesca Belfiore
The increased concerns about the effect of human activities on the climate have pushed natural gas among the most obvious solutions for the transition to a low-carbon economy. The growing importance and volumes of liquefied natural gas for transportation o ...
The Italian Association of Chemical Engineering2018Single-layer graphene membranes by crack-free transfer for gas mixture separation
Andreas Züttel, Duncan Thomas Lindsay Alexander, Emad Oveisi, Kumar Varoon Agrawal, Wen Luo, Mostapha Dakhchoune, Shiqi Huang, Guangwei He, Jing Zhao
The single-layer graphene film, when incorporated with molecular-sized pores, is predicted to be the ultimate membrane. However, the major bottlenecks have been the crack-free transfer of large-area graphene on a porous support, and the incorporation of mo ...
Nature Publishing Group2018Gaz naturel et tournant énergétique
Highlights of the research conducted at the Chaire Gaz Naturel – Pertrosvibri in the October edition of L’Extension. In the release of the L’Extension magazine the role of natural gas as an alternative source of energy was discussed. In the article, the im ...
2018Multi-Objective Optimization Programs and their Application to Amine Absorption Process Design for Natural Gas Sweetening
François Maréchal, Shivom Sharma
This chapter presents three MS Excel programs, namely, EMOO (Excel based Multi-Objective Optimization), NDS (Non-Dominated Sorting) and PM (Performance Metrics) useful for Multi-Objective Optimization (MOO) studies. The EMOO program is for finding non-domi ...
