The small-scale dynamo: Breaking universality at high Mach numbers

, 2013
(Abridged) The small-scale dynamo may play a substantial role in magnetizing the Universe under a large range of conditions, including subsonic turbulence at low Mach numbers, highly supersonic turbulence at high Mach numbers and a large range of ...

Dynamics and symmetries of flow reversals in turbulent convection

, 2011
Based on direct numerical simulations and symmetry arguments, we show that the large-scale Fourier modes are useful tools to describe the flow structures and dynamics of flow reversals in Rayleigh-B\'enard convection (RBC).

Nonlinear Dynamics of Capacitive Charging and Desalination by Porous Electrodes

, 2009
The rapid and efficient exchange of ions between porous electrodes and aqueous solutions is important in many applications, such as electrical energy storage by super-capacitors, water desalination and purification by capacitive deionization (or ...

Large Scale Structures a Gradient Lines: the case of the Trkal Flow

, 2010
A specific asymptotic expansion at large Reynolds numbers (R)for the long wavelength perturbation of a non stationary anisotropic helical solution of the force less Navier-Stokes equations (Trkal solutions) is effectively constructed of the Beltrami type

How does flow in a pipe become turbulent?

, 2007
The transition to turbulence in pipe flow does not follow the scenario familiar from Rayleigh-Benard or Taylor-Couette flow since the laminar profile is stable against infinitesimal perturbations for all Reynolds numbers.

Note on dust trapping in inviscid vortex pairs with unequal strengths

, 2010
We investigate theoretically the motion of tiny heavy passive particles transported in a plane inviscid flow consisting of two point vortices, in order to understand particle dispersion and trapping during vortex interaction.

Vortices within vortices: hierarchical nature of vortex tubes in turbulence

, 2013
The JHU turbulence database [1] can be used with a state of the art visualisation tool [2] to generate high quality fluid dynamics videos. In this work we investigate the classical idea that smaller structures in turbulent flows, while engaged in their ...

Linear stability analysis on the onset of viscous fingering due to a non monotonic viscosity profile for immiscible fluids

, 2017
The onset of viscous fingering in the presence of a non monotonic viscosity profile is investigated theoretically for two immiscible fluids. Classical fluid dynamics predicts that no unstable behavior may be observed when a viscous fluid pushes a less ...
