Targeted mechanical properties for optimal fluid motion inside artificial bone substitutes

Dominique Pioletti, Alexandre Terrier, Lalaonirina Rakotomanana Ravelonarivo, Luc Blecha

The goal of this study was to develop a method that identifies optimal elastic modulus, Poisson’s ratio, porosity and permeability values for mechanically stressed bone substitute. It was hypothesized that porous bone substitute that favors the transport o ...

Do Microscopic Organisms Feel Turbulent Flows?

Alfred Johny Wüest, Miki Hondzo

Microscopic organisms in aquatic environments are continuously exposed to a variety of physical and chemical conditions. Traditionally, it is accepted that due to their small size the physiology of microscopic organisms is not affected by the moving fluid ...

Model validation through experimental testbed: the fluid flow behavior example

Patrick Thiran, Adel Aziz

This testbed practice paper presents our efforts to validate an analytical model for fluid flow behavior in wireless mesh networks with an experimental evaluation. We have developed a fluid model for multihop communication in wireless mesh networks and ana ...

Plasticity and geophysical flows: A review

Christophe Ancey

The objective of this review is to examine how the concept of plasticity is used in geophysical fluid dynamics. Rapid mass movements such as snow avalanches or debris flows involve slurries of solid particles (ice, boulder, clay, etc.) within an interstiti ...

Caging Dynamics in a Granular Fluid

Pedro Miguel Nunes Pereira de Almeida Reis

We report an experimental investigation of the caging motion in a uniformly heated granular fluid for a wide range of filling fractions, ϕ. At low ϕ the classic diffusive behavior of a fluid is observed. However, as ϕ is increased, temporary cages develop ...

Measurements and Modeling of variable gravity effects on water distribution and flow in unsaturated porous media

Dani Or

Liquid behavior under reduced gravity conditions is of considerable interest for various components of life-support systems required for manned space missions. High costs and limited opportunities for spaceflight experiments hinder advances in reliable des ...

Adaptively sampled particle fluids

Mark Pauly

We present novel adaptive sampling algorithms for particle-based fluid simulation. We introduce a sampling condition based on geometric local feature size that allows focusing computational resources in geometrically complex regions, while reducing the num ...

Modeling Of Salt Tectonics

Alfio Quarteroni

In this work a general framework for the simulation of sedimentary basins in presence of salt structures is addressed. Sediments and evaporites are modeled as non-Newtonian fluids and the thermal effects induced by the presence of salt are taken into accou ...

Spherical pore replicated Microcellular Aluminium

Andreas Mortensen

A method is presented that extends the replication process for the manufacture of open-celled metallic foams to include foams with spherical cells. Such foams are produced to a wide range of relative densities, tested for mechanical behaviour and resistanc ...

Traveling liquid bridges in unsaturated fractured porous media

Dani Or

Interplay between capillary, gravity and viscous forces in unsaturated fractures gives rise to a range of complex flow phenomena. Evidence of highly intermittent fluxes, preferential and sustainable flow pathways lead to potentially significant flow focusi ...
