The influence of geometry and topology on axisymmetric mean-field dynamos
E. Covas, R. Tavakol, A. Tworkowski +3
We study the changes in the dynamical behaviour of axisymmetric spherical mean-field dynamo models produced by changes in their geometry and topology, by considering a two paramete…
Dynamics of Axisymmetric Truncated Dynamo Models
E. Covas, R. Tavakol
An important question regarding the study of mean field dynamo models is how to make precise the nature of their underlying dynamics. This is difficult both because relatively litt…
Mean Field Dynamos with Algebraic and Dynamic alpha-Quenchings
A. Tworkowski, E. Covas, R. Tavakol +1
Calculations for mean field dynamo models (in both full spheres and spherical shells), with both algebraic and dynamic --quenchings, show qualitative as well as quantitative dif…
In-out intermittency in PDE and ODE models of axisymmetric mean-field dynamos
Eurico Covas, Reza Tavakol, Peter Ashwin +2
Employing some recent results in dynamics of systems with invariant subspaces we find evidence in both truncated and full axisymmetric mean-field dynamo models of a recently discov…
Transverse instability for non-normal parameters
Peter Ashwin, Eurico Covas, Reza Tavakol
We consider the behaviour of attractors near invariant subspaces on varying a parameter that does not preserve the dynamics in the invariant subspace but is otherwise generic, in a…
