Numerical Analysis of Apparatus-Induced Dispersion for Density-Dependent Solute Transport in Porous Media
David Andrew Barry, Hong Zhang
The effects of apparatus-induced dispersion on nonuniform, density-dependent flow in a cylindrical soil column were investigated using a finite-element model. To validate the model, the results with an analytical solution and laboratory column test data we ...
2023Columnlike free-interface flows: symmetry breaking and linear instability
This thesis is dedicated to the analysis of a subclass of interfacial flows, columnlike free-interface flows, from two view angles: (i) the symmetry breaking under geometry-induced or external forces, (ii) their stability against infinitesimal disturbances ...
EPFL2023Swelling and shrinkage of partially saturated gas shales: from laboratory tests to an effective stress framework
Gas shale swelling during hydraulic stimulation is one of the major challenges in unconventional gas development. It is hypothesized that the large volumetric strain upon water imbibition is a consequence of dramatic changes in capillary pressure and disjo ...
EPFL2022Subharmonic parametric instability in nearly brimful circular cylinders: a weakly nonlinear analysis
François Gallaire, Alessandro Bongarzone, Francesco Viola
In labscale Faraday experiments, meniscus waves respond harmonically to small-amplitude forcing without threshold, hence potentially cloaking the instability onset of parametric waves. Their suppression can be achieved by imposing a contact line pinned at ...
CAMBRIDGE UNIV PRESS2022Liquid metal infiltration of silicon based alloys into porous carbonaceous materials. Part II: Experimental verification of modelling approaches by infiltration of Si-Zr alloy into idealized microchannels
Ludger Weber, Caroline Hain, Giovanni Bianchi, Alberto Ortona, Manoj Kondibhau Naikade
In this work, the mechanisms leading to the pore closure in reactive melt infiltration (RMI) of carbon by pure silicon and a near eutectic Si-8 at-pct Zr alloy at 1500 and 1700 degrees C under vacuum were studied. Various geometrical configurations of micr ...
ELSEVIER SCI LTD2022Approximate analytical solutions for assessing the effects of unsaturated flow on seawater extent in thin unconfined coastal aquifers
David Andrew Barry, Zhaoyang Luo
This study develops approximate analytical solutions for seawater extent in unconfined coastal aquifers considering unsaturated flow, and assuming steady-state, sharp-interface conditions, for both constant flux (flux-controlled aquifers) and constant head ...
2022Relaxation of capillary-gravity waves due to contact line nonlinearity: A projection method
François Gallaire, Alessandro Bongarzone, Francesco Viola
We present a physics-inspired mathematical model based on successive linear eigenmode projections to solve the relaxation of small-amplitude and two-dimensional viscous capillary-gravity waves with a phenomenological nonlinear contact line model. We show t ...
AIP Publishing2021A Wearable Autonomous Colorimetric Sweat Induction System for Sweat Analysis
Silvia Demuru, Brince Paul Kunnel
The wearable biochemical sweat sensor's capability to provide insight into molecular information of health dynamics ignites sweat analysis as a promising noninvasive diagnosis scheme for precision medicine. Here, we demonstrate, for the first time, a color ...
IEEE2021Understanding of the factors slowing down metakaolin reaction in limestone calcined clay cement (LC3) at late ages
Karen Scrivener, Paul Bowen, Yosra Briki, Mohsen Ben Haha, François Henri Avet
Factors which could explain the slowing down of the metakaolin reaction in LC3 blends are investigated. Portlandite availability and the presence of aluminium ions in the pore solution are shown not to be limiting factors. Hydrates can only precipitate in ...
PERGAMON-ELSEVIER SCIENCE LTD2021Experimental assessment of the hydro-mechanical behaviour of a shale caprock during CO2 injection
Lyesse Laloui, Alessio Ferrari, Eleni Stavropoulou, Alberto Minardi, Taeheon Kim
The presented experimental study focuses on the hydro-mechanical characterisation of a shale caprock (Opalinus Clay) in contact with carbon dioxide. The objective of this paper, consists in the evaluation of the material's sealing capacity in terms of entr ...
