On the concentration distribution in turbulent thermals
Ludovic Huguet, Victor Lherm, Renaud Deguen +2
Turbulent thermals emerge in a wide variety of geophysical and industrial flows, such as atmospheric cumulus convection and pollutant dispersal in oceans and lakes. When a buoyant…

A Unified Theory for Chaotic Mixing in Porous Media: from Pore Networks to Granular Systems
Daniel Lester, Joris Heyman, Yves Meheust +1
Recent studies have revealed the central role of chaotic stretching and folding at the pore scale in controlling mixing within porous media, whether the solid phase is discrete (as…

Mixing as a correlated aggregation process
Joris Heyman, Tanguy Le Borgne, Philippe Davy +1
Mixing describes the process by which solutes evolve from an initial heterogeneous state to uniformity under the stirring action of a fluid flow. Fluid stretching forms thin scalar…
