Statistics of velocity gradients in wall-bounded shear flow turbulence (2009)
Boeck, Thomas, Krasnov, Dmitry, Schumacher, Joerg
The statistical properties of velocity gradients in a wall-bounded turbulent channel flow are discussed on the basis of three-dimensional direct numerical simulations. Our analysis is concentrated on...

Low-Prandtl-number B\'enard-Marangoni convection in a vertical magnetic field (2009)
The effect of a homogeneous magnetic field on surface-tension-driven B\'{e}nard convection is studied by means of direct numerical simulations. The flow is computed in a rectangular domain with...
Krasnov, Dmitry, Zikanov, Oleg, Schumacher, Joerg, Boeck, Thomas
We examine the changes in kinetic energy dissipation of a turbulent channel flow caused by a spanwise magnetic field. The numerical study is based on our simulation data from [Krasnov, Zikanov,...
Large-scale intermittency of liquid-metal channel flow in a magnetic field (2008)
Boeck, Thomas, Krasnov, Dmitry, Thess, Andre, Zikanov, Oleg
We predict a novel flow regime in liquid metals under the influence of a magnetic field. It is characterised by long periods of nearly steady, two-dimensional flow interrupted by violent...
MHD turbulence in a channel with spanwise magnetic field (2008)
Krasnov, Dmitry, Zikanov, Oleg, Schumacher, Joerg, Boeck, Thomas
The effect of a uniform spanwise magnetic field on a turbulent channel flow is investigated for the case of low magnetic Reynolds number. DNS and LES computations are performed for two values of the...

Transition in a plane channel flow in the presence of a magnetic field. (2007)
ROSSI , Maurice, Dmitry Krasnov, Thomas Boeck, Oleg Zikanov
We investigate the linear evolution of perturbations in a magnetohydrodynamic channel flow with electrically insulating channel walls and a spanwise magnetic field. Linear optimal perturbation are...

Transition to Turbulence in the Hartmann Boundary Layer
Thess, AndrÉ, Krasnov, Dmitry, Boeck, Thomas, Zienicke, Egbert, Zikanov, Oleg, Moresco, Pablo, ...
The Hartmann boundary layer is a paradigm of magnetohydrodynamic (MHD) flows. Hartmann boundary layers develop when a liquid metal flows under the influence of a steady magnetic field. The present...
Subcritical instability of liquid metal channel flow in the presence of a spanwise magnetic field
Boeck, Thomas, Krasnov, Dmitry, Rossi, Maurice, Zikanov, Oleg
The linear and nonlinear evolution of perturbations is investigated in a magnetohydrodynamic channel flow with electrically insulating walls. The applied magnetic field is parallel to the walls and...
