How the Chemical Vapor Infiltration process can be optimized for the production of advanced composite and porous ceramics
|
Chemical Vapor Infiltration (CVI) is a specific materials processing technique allowing the insertion of a refractory material inside a porous medium at temperatures well below its melting point. It…

Discrete models, continuum models and scale transitions for drying porous media
|
Drying is of great practical importance but difficult to understand and describe, owed to transport phenomena in three different, complexly intermingled phases (solid skeleton, liquid-filled pores,…

Digital Workflow for analysis of flow on the pore scale.
|
Fluid transport in subsurface reservoirs is a key element to some of our main technical and environmental challenges we face today. Flow in reservoirs is flow in porous media and needs to be treated…

Transport of chemotactic bacteria in porous media with residual sources of oil-phase chemical pollutants
|
The removal of hydrocarbon contaminants from groundwater aquifers is particularly challenging due to their low solubility and the entrapment of residual oil-phase ganglia in layers with low…

Deformable porous media
|
In a porous medium, fluid flow is driven by a decreasing pore pressure in the direction of flow, as described by Darcy’s law. A deformable porous medium is one in which the solid skeleton deforms in…

Modelling the brain as a poroelastic medium
|
At the organ-level and at the time scale of seconds to weeks, the brain can be viewed as a poroelastic medium. Brain tissue is soft and elastic, and permeated by a number of networks filled with…
