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…
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…
