Magnetic field dynamos and magnetically triggered flow instabilities
Frank Stefani, Thomas Albrecht, Rainer Arlt +13
The project A2 of the LIMTECH Alliance aimed at a better understanding of those magnetohydrodynamic instabilities that are relevant for the generation and the action of cosmic magn…
Parametric instability in periodically perturbed dynamos
Andre Giesecke, Frank Stefani, Johann Herault
We examine kinematic dynamo action driven by an axisymmetric large scale flow that is superimposed with an azimuthally propagating non-axisymmetric perturbation with a frequency $ω…
Entrainment induced by waves at a density interface impinged by a turbulent jet
Johann Herault, Giulio Facchini, Michael Le Bars
Using water/salty-water laboratory experiments}, we investigate the mechanism of erosion by a turbulent jet impinging on a density interface, for moderate Reynolds and Froude numbe…
Experimental observation of 1/f noise in quasi-bidimensionnal turbulent flows
Johann Herault, François Pétrélis, Stephan Fauve
We report the experimental observation of noise in quasi-bidimensionnal turbulence of an electromagnetically forced flow. The large scale velocity exhibits this power…
Subcritical transition to turbulence of a precessing flow in a cylindrical vessel
Johann Herault, Thomas Gundrum, Andre Giesecke +1
The transition to turbulence in a precessing cylindrical vessel is experimentally investigated. Our measurements are performed for a { nearly-resonant} configuration with an initia…
Triadic resonances in non-linear simulations of a fluid flow in a precessing cylinder
A. Giesecke, T. Albrecht, T. Gundrum +2
We present results from three-dimensional non-linear hydrodynamic simulations of a precession driven flow in cylindrical geometry. The simulations are motivated by a dynamo experim…
