High-Rayleigh-number convection in porous-fluid layers
Thomas Le Reun, Duncan R. Hewitt
We present a numerical study of convection in a horizontal layer comprising a fluid-saturated porous bed overlain by an unconfined fluid layer. Convection is driven by a vertical,…

Evidence of the Zakharov-Kolmogorov spectrum in numerical simulations of inertial wave turbulence
Thomas Le Reun, Benjamin Favier, Michael Le Bars
Rotating turbulence is commonly known for being dominated by geostrophic vortices that are invariant along the rotation axis and undergo inverse cascade. Yet, it has recently been…

Internally heated porous convection: an idealised model for Enceladus' hydrothermal activity
Thomas Le Reun, Duncan R. Hewitt
Recent planetary data and geophysical modelling suggest that hydrothermal activity is ongoing under the ice crust of Enceladus, one of Saturn's moons. According to these models, hy…
