What is control of turbulence in crossed fields?
No full textVolchenkov D. What is control of turbulence in crossed fields? Communications in Nonlinear Science and Numerical Simulation. 2009;15(2):149-181.Convective instability in the cross-field system of thermonuclear reactors can be overridden by poloidal drifts. While in crossed fields, a long-time, large-scale turbulent regime, in which the eddies of some particular size are destined to persist longer than usual, would come into being. Perhaps, we may keep Such vortexes using them as tools for maintaining the stability of still an illusory construct of plasma fusion. (c) 2009 Elsevier B.V. All rights reserved

The bending instability in the vorticity transport through a turbulent flow. Feedback chaos controlling and dynamical symmetry breaking
No full textVolchenkov D. The bending instability in the vorticity transport through a turbulent flow. Feedback chaos controlling and dynamical symmetry breaking. INTERNATIONAL JOURNAL OF MODERN PHYSICS B. 2001;15(08):1147-1164.The model of a large-scale injection into a turbulent flow of immiscible fluid is considered. The long-time, large-scale asymptotic behavior of the energy dissipation rate epsilon is analyzed in the framework of renormalization group approach. It is shown that if the ordinary Kolmogorov dissipation regime (epsilon = const, in the inertial range) becomes unstable, the alternative asymptotic behavior would come true. In contrast to the standard Navier-Stokes turbulence, the alternative dissipation spectrum epsilon (k) has a minimum, which means that an optimal eddy size l exists in the model. This phenomenon provokes the flow into turbulence damping (the "bending effect" in combustion) or stimulates the magnetohydrodynamic system to a generation of a large-scale mean magnetic field ("turbulent dynamo" effect)
