Chaotic transients and hysteresis in an α <sup>2</sup> dynamo model

چکیده
The presence of chaotic transients in a nonlinear dynamo is investigated through numerical simulations the 3D magnetohydrodynamic equations. By using kinetic helicity flow as control parameter, hysteretic blowout bifurcation conjectured to be responsible for transition dynamo, leading sudden increase magnetic energy attractor. This high-energy hydromagnetic attractor suddenly destroyed boundary crisis when decreased. Both and generate long that are due, respectively, saddle relative

Hysteresis cycle in a turbulent, spherically bounded MHD dynamo model
We report direct numerical magnetohydrodynamic simulations at low magnetic Prandtl numbers of a turbulent two-cell flow in a bounded, spherical geometry, driven by a constant body force. The flow amplifies infinitesimal magnetic perturbations if the magnetic Reynolds number Rm is larger than a threshold Rmc, resulting in a self-excited equatorial magnetic dipole. However, finite amplitude pertu...
متن کاملAn Autonoumous Chaotic CNN Hysteresis Circuit
A new implementation of an autonomous hysteresis chaotic circuit using only two primitive cellular neural networks (CNN) cells is presented. Both computer simulations and laboratory measurements have confirmed the chaotic behavior and show the existence of the double scroll attractor. Key-Words: CNN, chaotic circuits, chaos, attractor, bifurcation, oscillator.
متن کاملChaos and chaotic transients in an aeroelastic system
Chaotic motions of a two dimensional airfoil with coupled structural nonlinearities, both in pitch as well as plunge degrees of freedom, are investigated via a numerical integration method. The original system of coupled integro-differential equations governing the motion of the present aeroelastic model is transformed into a simple system of six ODEs. Complex dynamical behaviors are revealed a...
متن کاملNon-linear and chaotic dynamo regimes
An update is given on the current status of solar and stellar dynamos. At present, it is still unclear why stellar cycle frequencies increase with rotation frequency in such a way that their ratio increases with stellar activity. The small-scale dynamo is expected to operate in spite of a small value of the magnetic Prandtl number in stars. Whether or not the global magnetic activity in stars i...
متن کاملPattern Recognition using Chaotic Transients
This paper proposes a novel nonlinear transient computation device described as the LTCM that uses the chaotic attractor provided by the Lorenz system of equations to perform pattern recognition. Previous work on nonlinear transient computation has demonstrated that such devices can process time varying input signals. This paper investigates the ability of the LTCM to correctly classify static,...
