Fourier Collocation and Reduced Basis Methods for Fast Modeling of Compressible Flows

A projection-based reduced order model (ROM) based on the Fourier collocation method is proposed for compressible flows. The incorporation of localized artificial viscosity model and filtering is pursued to enhance the robustness and accuracy of the ROM fo ...

Microscopic Origin of Nonlocal Rheology in Dense Granular Materials

Johan Alexandre Philippe Gaume

We study the microscopic origin of nonlocality in dense granular media. Discrete element simulations reveal that macroscopic shear results from a balance between microscopic elementary rearrangements occurring in opposite directions. The effective macrosco ...

Surfing the capillary wave: Wetting dynamics beneath an impacting drop

John Martin Kolinski, Ramin Kaviani

The initiation of contact between liquid and a dry solid is of great fundamental and practical importance. We experimentally probe the dynamics of wetting that occur when an impacting drop first contacts a dry surface. We show that, initially, wetting is m ...

Viscous 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, ...

Sloshing in a Hele-Shaw cell: experiments and theory

François Gallaire, Benjamin Jérémy Dollet, Francesco Viola

The response of the free liquid surface in a Hele-Shaw cell subjected to a horizontal oscillation is investigated. We study the low-oscillation-amplitude regime and we show, by varying the fluid viscosity, nu, and the forcing frequency, omega, that the rat ...

Effect of fluid viscosity on fault frictional behavior

Marie Estelle Solange Violay, Chiara Cornelio

Tectonic faults are often lubricated by viscous fluids which can have different natures e.g. gas, water, brine, melt and viscosities varying over 7 order of magnitude (from 10-4 for water to 103 Pa s-1 for a melt at high temperature). Moreover, understandi ...

Deformation of a soft helical filament in an axial flow at low Reynolds number

Pedro Miguel Nunes Pereira de Almeida Reis

We perform a numerical investigation of the deformation of a rotating helical filament subjected to an axial flow, under low Reynolds number conditions, motivated by the propulsion of bacteria using helical flagella. Given its slenderness, the helical rod ...

Interfacing dielectric elastomer actuators with liquids

Herbert Shea, Samuel Rosset, Alexandre Poulin, Luc Maffli

Methods and materials for liquid encapsulation in thin (19 μm) silicone membranes are presented in this work. A set of 12 liquids including solvents, oils, silicone pre-polymers and one ionic liquid are experimentally tested. We show that all selected liqu ...
