The global flow state in a precessing cylinder
André Giesecke, Tobias Vogt, Federico Pizzi +4
We examine the fluid flow forced by precession of a rotating cylindrical container using numerical simulations and experimental flow measurements with ultrasonic Doppler velocimetr…
Generation of interfacial waves by rotating magnetic fields
Gerrit Maik Horstmann, Yakov Nezihovski, Thomas Gundrum +1
Interfacial waves arising in a two-phase swirling flow driven by a low-frequency rotating magnetic field (RMF) are studied. At low RMF frequencies, of the order of 1-10 Hz, the osc…
Numerical and theoretical framework for the DRESDYN precession dynamo experiment
F. Pizzi, A. Giesecke, J. Simkanin +3
The upcoming DRESDYN (DREsden Sodium facility for DYNnamo and thermohydraulic studies) precession experiment will test the possibility to achieve magnetohydrodynamic dynamo action…
Synchronizing the helicity of Rayleigh-Bénard convection by a tide-like electromagnetic forcing
Peter Jüstel, Sebastian Röhrborn, Sven Eckert +4
We present results on the synchronization of the helicity in a liquid-metal Rayleigh-Bénard (RB) experiment under the influence of a tide-like electromagnetic forcing with azimutha…
The effect of nutation angle on the flow inside a precessing cylinder and its dynamo action
V. Kumar, F. Pizzi, A. Giesecke +4
The effect of the nutation angle on the flow inside a precessing cylinder is experimentally explored and compared with numerical simulations. The focus is laid on the typical break…
Experimental investigation of the return flow instability in magnetic spherical Couette flow
Jude Ogbonna, Ferran Garcia, Thomas Gundrum +2
We conduct magnetic spherical Couette (MSC) flow experiments in the return flow instability regime with GaInSn as the working fluid, and the ratio of the inner to the outer sphere…
