In the framework of DRESDYN (DREsden Sodium facility for DYNnamo and thermohydraulic studies) we study the hy-
drodynamics of a fluid contained in a precessing cylinder. Here we focus on turbulence properties of the flow in dependence of the
precession angle as well as Reynolds number and Poincaré number (ratio of the frequency of the precessional system and the cylinder
itself). The main result is a characteristic peak in the dissipation around Po = 0.1 which goes along with a local maximum of turbulent
kinetic energy.
