DeepBND: A machine learning approach to enhance multiscale solid mechanics
Annalisa Buffa, Simone Deparis, Pablo Antolin Sanchez, Felipe Figueredo Rocha
Effective properties of materials with random heterogeneous structures are typically determined by homogenising the mechanical quantity of interest in a window of observation. The entire problem setting encompasses the solution of a local PDE and some aver ...
2023Flowing Gas Experiments Reveal Mechanistic Details of Interfacial Reactions on a Molecular Level at Knudsen Flow Conditions
Christian Ludwig, Michel Rossi, Riccardo Iannarelli
Knudsen flow experiments and its interpretation in terms of adsorption/desorption kinetics as well as quantitative uptake on substrates of interest is presented together with the description of critical design parameters of the Knudsen Flow Reactor (KFR). ...
2022Single-phase SPH modelling of plunge pool dynamic pressures at a near-prototype scale
The turbulent plunging jet of a nearly incompressible fluid into a stagnant fluid is of great importance in many practical applications, especially for the engineering of hydropower. As an example, the dynamic load exerted by the impact of turbulent high-v ...
TAYLOR & FRANCIS LTD2021Continuously-fed density currents over impermeable and porous substrates
Gravity currents are buoyancy-driven flows having a significant impact on the environment and human life. They can be observed in a vast range of natural and anthropogenic scenarios, such as seawater and freshwater, the atmosphere, or industrial processes. ...
EPFL2020Effective stress jump across membranes
François Gallaire, Giuseppe Antonio Zampogna
A macroscopic condition to simulate the interaction between an incompressible fluid flow and a permeable micro-structured rigid surface (i.e. a thin membrane) has been developed using multiscale homogenization and matching asymptotic expansions between the ...
CAMBRIDGE UNIV PRESS2020Continuously-fed gravity currents propagating over a finite porous substrate
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
We present the results of laboratory investigations of continuously-fed density currents that propagate first over a smooth horizontal bed and then over a porous substrate of limited length. Inflow discharge, initial excess density, and substrate porositie ...
2019Theoretical framework to analyze the combined effect of surface tension and viscosity on the damping rate of sloshing waves
François Gallaire, Francesco Viola
Gravity force, surface tension, oscillating boundary layers, viscous dissipation, static meniscus, contact angle hysteresis, and moving contact lines are typical features of sloshing dynamics. All these ingredients influence capillary-gravity waves in a co ...
AMER PHYSICAL SOC2018Viscous growth and rebound of a bubble near a rigid surface
François Gallaire, Giacomo Gallino
Motivated by the dynamics of microbubbles near catalytic surfaces in bubble-powered microrockets, we consider theoretically the growth of a free spherical bubble near a flat no-slip surface in a Stokes flow. The flow at the bubble surface is characterised ...
CAMBRIDGE UNIV PRESS2018Viscous Taylor droplets in axisymmetric and planar tubes: from Bretherton’s theory to empirical models
François Gallaire, Gioele Mariano Nicolò Balestra, Lailai Zhu
The aim of this study is to derive accurate models for quantities characterizing the dynamics of droplets of non-vanishing viscosity in capillaries. In particular, we propose models for the uniform-film thickness separating the droplet from the tube walls, ...
2018Thermal Diffusion in Binary Mixtures: Transient Behavior and Transport Coefficients from Equilibrium and Nonequilibrium Molecular Dynamics
Equilibrium and nonequilibrium molecular dynamics simulations are combined to compute the full set of coefficients that appear in the phenomenological equations describing thermal transport in a binary mixture subject to a constant thermal, gradient The Dy ...
