Flow, deformation, and reaction patterns in porous media
We seek to understand, predict and eventually control the patterns that emerge in porous and granular materials by fluid flow. Examples include the creation of flow-induced preferential conduits (fingers or channels) by hydrodynamic instabilities, fracturing, dissolution and deposition of solutes and particles. The acquired knowledge would be applied to a range of applications, ranging from 3-D printing, coating, microfluidics, and filtering to water resources, carbon geo-sequestration, sediment erosion and enhanced energy recovery.

Elaborated Description
We seek to gather an interdisciplinary research community, and develop novel ideas to understand, predict and eventually control the patterns that emerge in porous and granular materials by fluid flow. Examples include:
i) preferential flow pathways induced by mechanical and/or chemical modifications of the solid matrix such as fracturing and dissolution;
ii) fluid fingers associated with microstructural heterogeneity and hydrodynamic instabilities;
iii) Thermo/turbophoresis, precipitation, and deposition of solutes and particles in channels and porous structures.
In these phenomena, coupling of fluid flow and fluid-fluid or fluid-solid interactions leads to highly focused flow and deformation, which, on top of producing enchanting patterns also provide enhanced migration pathways for mass and heat and alter the mechanical and chemical state of these materials. Relevant applications include many natural and industrial processes which span a wide range of scales, from 3-D printing, coating, microfluidics, filtering, and combustion to geophysical processes such as subsurface contamination and remediation, hazardous waste storage, carbon geo-sequestration, sediment erosion and enhanced recovery of oil, gas and geothermal energy.
This SIG will provide a platform to bring together scientists with various experimental, theoretical and numerical expertise from diverse fields including fluid mechanics, earth sciences, soil mechanics, civil and mechanical engineering, mathematics and physics. Together, we will tackle some of the most burning challenges related to processes in which fluid flow patterning is key. A spacial focus will be given to environmental and energy applications involving fluid injection and transport of fluids and solutes in the subsurface, with the aim of transferring the methodologies in this field to other areas cited above.
