From coating flow patterns to porous body wake dynamics via multiscale models
Multiscale phenomena are involved in countless problems in fluid mechanics. Coating flows are known to exhibit a broad variety of patterns, such as wine tears in a glass and dripping of fresh paint applied on a wall. Coating flows are typically modeled und ...
EPFL2022Steadily Moving Semi-Infinite Hydraulic Fracture in a Poroelastic Media
Brice Tanguy Alphonse Lecampion, Andreas Möri
Linear elastic fracture mechanics has been widely used to describe the propagation of hydraulic fractures in rocks [1]. The embedding material is generally considered to be elastic and permeable, but the fluid exchange between the fracture and the media is ...
2022On predicting pore fluid pressure changes in unsaturated porous media subject to undrained processes
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Predicting the induced change of fluid pressure in an unsaturated porous medium during undrained loading/unloading processes is challenging because two different fluids (a liquid and a gaseous solution) and a mixture of solid particles are involved. The re ...
2021Hydro-mechanical coupling in porous rocks: hidden dependences to the microstructure?
While hydro-mechanical coupling in rocks is generally well understood, exotic rock poroelastic responses-such as unexpected dependence to fluid diffusion time and low skeleton moduli-have been reported. Hydro-mechanical coupling, or poroelasticity, explain ...
OXFORD UNIV PRESS2021Three-dimensional fluid-driven stable frictional ruptures
Brice Tanguy Alphonse Lecampion, Alexis Alejandro Sáez Uribe
We investigate the quasi-static growth of a fluid-driven frictional shear crack that propagates in mixed mode (II+III) on a planar fault interface that separates two identical half-spaces of a three-dimensional solid. The fault interface is characterized b ...
2021Experimental and Numerical Study on Scour-Protection Methods in a Stilling Basin: Case Study of Chancy-Pougny Dam
Anton Schleiss, Giovanni De Cesare, Erik Bollaert, Sabine Chamoun, Davide Wüthrich
Chancy-Pougny is a run-of-river dam on the Swiss–French border constructed in the early 1920s. Since its commissioning, the operation of the four spillway gates has been responsible for a progressive erosion of the stilling basin. The future scour potentia ...
2021Numerical characterization and engineering of transport in morphologically complex heterogeneous media
A multi-scale numerical methodology for the assessment of radiation and optical characteristics of complex structured soot-contaminated snow layers was investigated first. The methodology accounted for the exact morphology at the various scales and utilize ...
EPFL2021Experimental studies of hydro-mechanical couplings in Enhanced Geothermal Reservoirs
Enhanced Geothermal Systems (EGS) allow for worldwide geothermal electricity production. They target deep (3-5 km), fractured rock reservoirs whose permeability is artificially increased through hydraulic stimulations (fluid injections). The injections mod ...
EPFL2020Mechanical and hydraulic transport properties of transverse-isotropic Gneiss deformed under deep reservoir stress and pressure conditions
Marie Estelle Solange Violay, Mateo Alejandro Acosta
In central Europe, many geo-energy reservoirs have revealed to be hosted in transverse isotropic crystalline rock, where the rock's mechanical and hydraulic transport properties are poorly constrained. Here, we performed triaxial experiments on Cresciano G ...
PERGAMON-ELSEVIER SCIENCE LTD2020Depth-averaged momentum equation for gravity currents with varying density: coefficient in pressure term
Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
Gravity currents are often modelled by means of shallow water equations (SWEs). In these models, simplifications such as the consideration of a constant layer-averaged density are common. This note presents the complete and general derivation of a 2D depth ...
