Surface quasigeostrophic turbulence: The refined study of an active scalar
Nicolas Valade, Jérémie Bec, Simon Thalabard
SQG describes the 2D active transport of a scalar field, such as temperature, which -- when properly rescaled -- shares the same physical dimension of length/time as the advecting…
Anomalous dissipation and spontaneous stochasticity in deterministic surface quasi-geostrophic flow
Nicolas Valade, Simon Thalabard, Jeremie Bec
Surface quasi geostrophy (SQG) describes the two-dimensional active transport of a temperature field in a strongly stratified and rotating environment. Besides its relevance to geo…
Modeling compressed turbulent plasma with rapid viscosity variations
Sébastien Thévenin, Nicolas Valade, Benoit-Joseph Gréa +2
We propose two-equations models in order to capture the dynamics of a turbulent plasma undergoing compression and experiencing large viscosity variations. The models account for po…
Folding instabilities in non-Newtonian viscous sheets: shear thinning and shear thickening effects
Anselmo Pereira, Nicolas Valade, Elie Hachem +1
In this work, we extend the analyses devoted to Newtonian viscous fluids previously reported by Ribe [Physical Review E 68, 036305 (2003)], by investigating shear thickening (dilat…
