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…
Mode Conversion and Period Doubling at Plasma- Unity in an Alfvén-Wave Experiment with Liquid Rubidium
F. Stefani, J. Forbriger, Th. Gundrum +2
We report Alfvén-wave experiments with liquid rubidium at the Dresden High Magnetic Field Laboratory (HLD). Reaching up to 63 T, the pulsed magnetic field exceeds the critical valu…
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…
Magnetic material in mean-field dynamos driven by small scale helical flows
Andre Giesecke, Frank Stefani, Gunter Gerbeth
We perform kinematic simulations of dynamo action driven by a helical small scale flow of a conducting fluid in order to deduce mean-field properties of the combined induction acti…
DRESDYN - A new facility for MHD experiments with liquid sodium
F. Stefani, S. Eckert, G. Gerbeth +5
The DREsden Sodium facility for DYNamo and thermohydraulic studies (DRESDYN) is intended as a platform both for large scale experiments related to geo- and astrophysics as well as…
Magnetic Field Saturation in the Riga Dynamo Experiment
Agris Gailitis, Olgerts Lielausis, Ernests Platacis +7
After the dynamo experiment in November 1999 had shown magnetic field self-excitation in a spiraling liquid metal flow, in a second series of experiments emphasis was placed on the…
Detection of a flow induced magnetic field eigenmode in the Riga dynamo facility
Agris Gailitis, Olgerts Lielausis, Sergej Dement'ev +8
In an experiment at the Riga sodium dynamo facility, a slowly growing magnetic field eigenmode has been detected over a period of about 15 seconds. For a slightly decreased propell…
