Computation of kinematic and magnetic -effect and eddy diffusivity tensors by Padé approximation
Sílvio M. A. Gama, Roman Chertovskih, Vladislav Zheligovsky
We present examples of Padé approximation of the -effect and eddy viscosity/diffusivity tensors in various flows. Expressions for the tensors derived in the framework of the sta…
Pointwise vanishing velocity helicity of a flow does not preclude magnetic field generation
Alexander Andrievsky, Roman Chertovskih, Vladislav Zheligovsky
Pointwise zero velocity helicity density is shown not to prevent steady flows from acting as kinematic dynamos. We present numerical evidences that such flows can generate both sma…
Negative magnetic eddy diffusivity due to oscillogenic -effect
Alexander Andrievsky, Roman Chertovskih, Vladislav Zheligovsky
We study large-scale kinematic dynamo action of steady mirror-antisymmetric flows of incompressible fluid, that involve small spatial scales only, by asymptotic methods of the mult…
Magnetic field generation by pointwise zero-helicity three-dimensional steady flow of incompressible electrically conducting fluid
A. Rasskazov, R. Chertovskih, V. Zheligovsky
We introduce six families of three-dimensional space-periodic steady solenoidal flows, whose kinetic helicity density is zero at any point. Four families are analytically defined.…
Negative magnetic eddy diffusivities from test-field method and multiscale stability theory
Alexander Andrievsky, Axel Brandenburg, Alain Noullez +1
The generation of large-scale magnetic field in the kinematic regime in the absence of an alpha-effect is investigated by following two different approaches, namely the test-field…
Numerical evidence of breaking of vortex lines in an ideal fluid
E. A. Kuznetsov, O. M. Podvigina, V. A. Zheligovsky
Emergence of singularity of vorticity at a single point, not related to any symmetry of the initial distribution, has been demonstrated numerically for the first time. Behavior of…
