On the enstrophy in a precessing cylinder

Within the project DRESDYN (DREsden Sodium facility for DYNnamo and thermohy-
draulic studies) a precession driven a fluid flow of liquid sodium will be examined with regard
to the possibility of serving as source for magnetic field generation. Hydrodynamic studies
and simulations are essential to understand the behaviour of the fluid flow. Here we present
the direct numerical simulations of a fluid flow forced by precession conducted in a cylindrical
domain, with the focus on the relation between dissipation and enstrophy.
