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…
Four-frequency solution in a magnetohydrodynamic Couette flow as a consequence of azimuthal symmetry breaking
Ferran Garcia, Martin Seilmayer, André Giesecke +1
The occurrence of magnetohydrodynamic (MHD) quasiperiodic flows with four fundamental frequencies in differentially rotating spherical geometry is understood in terms of a sequence…
Long term time dependent frequency analysis of chaotic waves in the weakly magnetized spherical Couette system
Ferran Garcia, Martin Seilmayer, André Giesecke +1
The long therm behavior of chaotic flows is investigated by means of time dependent frequency analysis. The system under test consists of an electrically conducting fluid, confined…
Phase coherence and phase jumps in the Schwabe cycle
F. Stefani, J. Beer, A. Giesecke +4
Guided by the working hypothesis that the Schwabe cycle of solar activity is synchronized by the 11.07 years alignment cycle of the tidally dominant planets Venus, Earth and Jupite…
Chaotic wave dynamics in weakly magnetised spherical Couette flows
Ferran Garcia, Martin Seilmayer, André Giesecke +1
Direct numerical simulations of a liquid metal filling the gap between two concentric spheres are presented. The flow is governed by the interplay between the rotation of the inner…
The Multivariate Extension of the Lomb-Scargle Method
Martin Seilmayer, Ferran Garcia Gonzalez, Thomas Wondrak
The common methods of spectral analysis for multivariate (-dimensional) time series, like discrete Frourier transform (FT) or Wavelet transform, are based on Fourier series to d…
