Mean-field helicity in random -dynamo twisted flows
Garcia de Andrade
Here, an analytical version of numerical results is obtained in case of considering the laminar non-turbulent limit, of a twisted Riemannian thin flux tube. It is shown that the ma…
Stretch-Twist-Fold and slow filamentary dynamos in liquid sodium Madison Dynamo Experiments
Garcia de Andrade
Recently Ricca and Maggione [MHD (2008)] have presented a very simple and interesting model of stretch-twist-fold dynamo in diffusive media based on numerical simulations of Rieman…
Dynamo experiments in torsioned toroidal devices
Garcia de Andrade
Recently Shukurov, Stepanov and Sokoloff [\textbf{Phys. Rev. E 69 (2008)}] have suggested that Moebius flows can support dynamo action. In this report, it is shown that a steady pe…
Lyapunov spectra instability of chaotic dynamo Ricci flows in twisted magnetic flux tubes
Garcia de Andrade
Previously Casetti, Clementi and Pettini [\textbf{Phys.Rev.E \textbf{54},6,(1996)}] have investigated the Lyapunov spectrum of Hamiltonian flows for several Hamiltonian systems by…
Non-Riemannian geometrical asymmetrical damping stresses on the Lagrange instability of shear flows
Garcia de Andrade
It is shown that the physical interpretation of Elie Cartan three-dimensional space torsion as couple asymmetric stress, has the effect of damping, previously Riemannian unstable C…
Stable curved solitonic surfaces in nonholonomic frame
Garcia de Andrade
Assuming the stability of soliton surfaces of vanishing Ricci sectional curvature of soliton metric in the nonholonomic frame, we find a solution for the metric in the approximatio…
Ricci curvature and geodesic flows stability in Riemannian twisted flux tubes
Garcia de Andrade
Ricci and sectional curvatures of twisted flux tubes in Riemannian manifold are computed to investigate the stability of the tubes. The geodesic equations are used to show that in…
An example of anti-dynamo conformal Arnold metric
Garcia de Andrade
A 3D metric conformally related to Arnold cat fast dynamo metric: is shown to present a behaviour of non-dynamos where the magnetic…
