Density-dependent solute transport in a layered hyporheic zone

David Andrew Barry, Mohsen Cheraghi, Qihao Jiang

Hyporheic exchange is affected by bedform geometry, which induces complex flow paths within the bedform. Additional factors that influence flow and solute transport in the hyporheic zone are layered profile sediments and density-driven flow. This study exp ...

Exploring the use of native spider silk as an optical fibre for chemical sensing

Luc Thévenaz, Kenny Hey Tow, Isabelle Dicaire, Desmond Chow Ming Chia

A spider uses up to seven different types of silk, all having specific functions, as building material, weapon and sensory organ to detect the presence of preys on its web. Recently, scientists have put under the limelight the extraordinary properties of t ...

3D spacers enhance flow kinetics in resin transfer molding with woven fabrics

Véronique Michaud, Baris Çaglar, Damiano Salvatori

Impregnation time in Resin Transfer Molding (RTM) is directly proportional to resin viscosity and inversely proportional to fabric permeability, limiting the use of high-viscosity resins with conventional reinforcements. In this study, we show how to reduc ...

Multiscale methods for Stokes flow in heterogeneous media

Ondrej Budác

Fluid flow in porous media is a multiscale process where the effective dynamics, which is often the goal of a computation, depends strongly on the porous micro structure. Resolving the micro structure in the whole porous medium can, however, be prohibitive ...
