Subcritical transition to turbulence in quasi-two-dimensional shear flows
Christopher J. Camobreco, Alban Pothérat, Gregory J. Sheard
The transition to turbulence in conduits is among the longest-standing problems in fluid mechanics. Challenges in producing or saving energy hinge on understanding promotion or sup…

Low MHD turbulence: the role of boundaries
Alban Pothérat
In this short review, we present the main known features of MHD Turbulence at Low Magnetic Reynolds number, for which the flow isn't intense nor electrically conductive enough to d…
Dean flow and vortex shedding in a three-dimensional 180 sharp bend
Alban Pothérat, Lintao Zhang
We present a detailed analysis of the flow in a 180 sharp bend of square cross-section. Besides numerous applications where this generic configuration is found, its main fundamenta…
Transition to chaos in an acoustically-driven cavity flow
Gaby Launay, Tristan Cambonie, Daniel Henry +2
We consider the unsteady regimes of an acoustically-driven jet that forces a recirculating flow through successive reflections on the walls of a square cavity. The specific questio…
Linear stability of horizontal, laminar fully developed, quasi-two-dimensional liquid metal duct flow under a transverse magnetic field and heated from below
Tony Vo, Gregory J. Sheard, Alban Pothérat
This study considers the linear stability of Poiseuille-Rayleigh-Bénard flows, subjected to a transverse magnetic field to understand the instabilities that arise from the complex…
Do magnetic fields enhance turbulence at low magnetic Reynolds number ?
Alban Pothérat, Rico Klein
Imposing a magnetic field on a turbulent flow of electrically conducting fluid incurs the Joule effect. A current paradigm is that the corresponding dissipation increases with the…
Onset of plane layer magnetoconvection at low Ekman number
Kélig Aujogue, Alban Pothérat, Binod Sreenivasan
We study the onset of magnetoconvection between two infinite horizontal planes subject to a vertical magnetic field aligned with background rotation. In order to gain insight into…
Spectral Direct Numerical Simulations of low Rm MHD channel flows based on the least dissipative modes
Kacper Kornet, Alban Pothérat
We put forward a new type of spectral method for the direct numerical simulation of flows where anisotropy or very fine boundary layers are present. The mean idea is to take advant…
Formation mechanism of hairpin vortices in the wake of a truncated square cylinder in a duct
Vincent Dousset, Alban Pothérat
We investigate the laminar shedding of hairpin vortices in the wake of a truncated square cylinder placed in a duct, for Reynolds numbers around the critical threshold of the onset…
Direct Numerical Simulations of Low- MHD turbulence based on the least dissipative modes
Alban Pothérat, Vitali Dymkou
We present a new spectral method for the Direct Numerical Simulation of Magnetohydrodynamic turbulence at low Magnetic Reynolds number. The originality of our approach is that inst…
