Large-scale intermittency of liquid-metal channel flow in a magnetic field
Thomas Boeck, Dmitry Krasnov, Andre Thess +1
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 v…
Direct Assessment of Vorticity Alignment with Local and Nonlocal Strain Rates in Turbulent Flows
Peter E. Hamlington, Jörg Schumacher, Werner J. A. Dahm
A direct Biot-Savart integration is used to decompose the strain rate into its local and nonlocal constituents, allowing the vorticity alignment with the local and nonlocal strain…
MHD turbulence in a channel with spanwise magnetic field
Dmitry Krasnov, Oleg Zikanov, Joerg Schumacher +1
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…
Fine-scale statistics of temperature and its derivatives in convective turbulence
M. S. Emran, J. Schumacher
We study the fine-scale statistics of temperature and its derivatives in turbulent Rayleigh-Benard convection. Direct numerical simulations are carried out in a cylindrical cell wi…
Lagrangian dispersion and heat transport in convective turbulence
Joerg Schumacher
Lagrangian studies of the local temperature mixing and heat transport in turbulent Rayleigh-Benard convection are presented, based on three-dimensional direct numerical simulations…
Local and Nonlocal Strain Rate Fields and Vorticity Alignment in Turbulent Flows
Peter E. Hamlington, Jörg Schumacher, Werner J. A. Dahm
Local and nonlocal contributions to the total strain rate tensor at any point in a flow are formulated from an expansion of the vorticity field in a local spherical neighborhood of…
