Abstract
Experimentally and numerically, we investigate the impact of a spatially homogeneous, direction-dependent tensorial viscosity on a turbulent flow. The anisotropy is induced by the magnetic alignment of prolate tracer particles in an external magnetic field. In the experiment, a spatial fixation of global flow modes in a von Kármán flow is observed. In the direct numerical simulation, the anisotropy dominates at small scales and causes field-parallel alignment of vortices and a decrease of the energy spectra in the same direction. Show more
