    O. Podvigina
    17/10/2011, 11:00
    Dynamical systems, equivariant under the action of a non-trivial symmetry group, can possess structurally stable heteroclinic cycles. We consider stability properties of a class of structurally stable heteroclinic cycles in $\R^n$, which we call heteroclinic cycles of type Z. It is well-known that a heteroclinic cycle, that is not asymptotically stable, can attract nevertheless a positive...

    D. Mitra (NORDITA)
    17/10/2011, 16:15
    We consider mean-field dynamo models with fluctuating \alpha effect, both with and without shear. The \alpha effect is chosen to be Gaussian white noise with zero mean and given covariance. We show analytically that the mean magnetic field does not grow, but, in an infinitely large domain, the mean-squared magnetic field shows exponential growth of the fastest growing mode at a rate...

  10. 259. Negative effective magnetic pressure instability
    A. Brandenburg
    18/10/2011, 09:45
    We present the first demonstration of the negative effective magnetic pressure instability in direct numerical simulations of stably stratified, externally forced, isothermal hydromagnetic turbulence in the regime of large plasma beta. By the action of this instability, an initially uniform horizontal magnetic field forms flux concentrations whose scale is large compared to the turbulent...

  12. 261. Relaxation of Galerkin-Truncated Gyrokinetic, and back to Magenticfluids
    J-Z Zhu
    18/10/2011, 11:30
    The gyrokinetic absolute equilibrium will be reviewed. Some numerical results of gyrokinetic simulations will be presented. Two-fluid magneticfluid absolute equilibrium is used to investigate two-fluid effects, effects of various helicities et al. This talk try to bring some new insights into the kinetic and two-fluid effects in magnetized plasma turbulence in fusion device, space and...

  13. 262. Condensates in two dimensional turbulence
    C-K Chan
    18/10/2011, 12:00
    We derive and numerically confirm that the saturation of energy condensation in two-dimensional turbulence is governed by the balance between forcing and small-scale dissipation. The time scale of saturation is inversely proportional to the viscosity but the saturation energy level is determined by both viscosity and the forcing scale. It is shown that, because the energy dissipation...

  20. 269. Role of polymers in the mixing of Rayleigh-Taylor turbulence
    A Mazzino
    19/10/2011, 11:45
    The role of polymer additives on Rayleigh-Taylor turbulence is investigated by means of direct numerical simulations (DNS) of Oldroyd-B viscoelastic model. The dynamics of polymer elongations follows adiabatically the self-similar evolution of the turbulent mixing layer and shows the appearance of a strong feedback on the flow which originates a cut off for polymer elongations. The...
