Why dynamos are prone to reversals
Frank Stefani, Gunter Gerbeth, Uwe Guenther +1
In a recent paper (Phys. Rev. Lett. 94 (2005), 184506; physics/0411050) it was shown that a simple mean-field dynamo model with a spherically symmetric helical turbulence parameter…
Contactless inductive flow tomography
Frank Stefani, Thomas Gundrum, Gunter Gerbeth
The three-dimensional velocity field of a propeller driven liquid metal flow is reconstructed by a contactless inductive flow tomography (CIFT). The underlying theory is presented…
The MHD alpha^2-dynamo, Z_2-graded pseudo-Hermiticity, level crossings and exceptional points of branching type
U. Guenther, F. Stefani, G. Gerbeth
The spectral branching behavior of the 2x2 operator matrix of the magneto-hydrodynamic alpha^2-dynamo is analyzed numerically. Some qualitative aspects of level crossings are brief…
Inverse Problems in Magnetohydrodynamics: Theoretical and Experimental Aspects
Frank Stefani, Thomas Gundrum, Gunter Gerbeth +2
We consider inverse problems related to the velocity reconstruction in electrically conducting fluids from externally measured magnetic fields. The underlying theory is presented i…
