Dynamic multiphase flow triggers chaotic mixing in porous media
Gaute Linga, Kevin Pierce, Marcel Moura +3
Solute mixing plays a pivotal role in a broad spectrum of chemical and biological processes across natural and engineered porous media. However, current understanding of mixing dyn…
How pore-scale disorder controls fluid stretching in porous media
J. Kevin Pierce, Tanguy Le Borgne, Francois Renard +1
Fluid stretching in porous media governs the mixing of reactants, contaminants, and nutrients, yet how the solid microstructure controls the stretching statistics remains poorly un…
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…
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…
