Tunable transport in bi-disperse porous materials with vascular structure
Olivier Vincent, Théo Tassin, Erik J. Huber +1
We study transport in synthetic, bi-disperse porous structures, with arrays of microchannels interconnected by a nanoporous layer. These structures are inspired by the xylem tissue…

Fingering convection in a spherical shell
T. Tassin, T. Gastine, A. Fournier
We use 123 three dimensional direct numerical simulations to study fingering convection in non-rotating spherical shells. We investigate the scaling behaviour of the flow lengthsca…

Geomagnetic semblance and dipolar-multipolar transition in top-heavy double-diffusive geodynamo models
Théo Tassin, Thomas Gastine, Alexandre Fournier
Convection in the liquid outer core of the Earth is driven by thermal and chemical perturbations. The main purpose of this study is to examine the impact of double-diffusive convec…
