Kelvin-Helmholtz versus Hall Magneto-shear instability in astrophysical flows [PDF]
, 2014 We study the stability of shear flows in a fully ionized plasma. Kelvin-Helmholtz is a well known, macroscopic and ideal shear-driven instability. In sufficiently low density plasmas, also the microscopic Hall magneto-shear instability can take place. We

Global bifurcations to subcritical magnetorotational dynamo action in Keplerian shear flow [PDF]
, 2013 Magnetorotational dynamo action in Keplerian shear flow is a three-dimensional, non-linear magnetohydrodynamic process whose study is relevant to the understanding of accretion processes and magnetic field generation in astrophysics.

Hydrodynamics of Micro-swimmers in Films [PDF]
, 2016 One of the principal mechanisms by which surfaces and interfaces affect microbial life is by perturbing the hydrodynamic flows generated by swimming. By summing a recursive series of image systems we derive a numerically tractable approximation to the ...

Aggregation of silica nanoparticles in concentrated suspensions under turbulent, shear and extensional flows. [PDF]
, 2013 The production of nanoparticles in concentrated suspensions requires strict control of the stability of the systems which are strongly influenced by the physico-chemical properties and the hydrodynamic conditions they are placed in. This study deals with

The Role of the Magnetorotational Instability in the Sun [PDF]
, 2014 We calculate growth rates for nonaxisymmetric instabilities including the magnetorotational instability (MRI) throughout the Sun. We first derive a dispersion relation for nonaxisymmetric instability including the effects of shear, convective buoyancy ...

Bifurcation in electrostatic resistive drift wave turbulence
, 2007 The Hasegawa-Wakatani equations, coupling plasma density and electrostatic potential through an approximation to the physics of parallel electron motions, are a simple model that describes resistive drift wave turbulence. We present numerical analyses of

On the transition to turbulence of wall-bounded flows in general, and plane Couette flow in particular [PDF]
, 2014 The main part of this contribution to the special issue of EJM-B/Fluids dedicated to Patrick Huerre outlines the problem of the subcritical transition to turbulence in wall-bounded flows in its historical perspective with emphasis on plane Couette flow ...

Observations of the stratorotational instability in rotating concentric cylinders [PDF]
, 2016 We study the stability of density stratified flow between co-rotating vertical cylinders with rotation rates $\Omega_o < \Omega_i$ and radius ratio $r_i/r_o=0.877$, where subscripts $o$ and $i$ refer to the outer and inner cylinders.
