Kinematic dynamo in three - and two-dimensional chaotic
Date/Time: 12:10 20-Oct-2019
The growth of small-scale magnetic field fluctuations in chaotic flow of conducting fluid is studied. It is shown that this enhancement terminates in three dimensional case by back reaction of the magnetic field on the flow, but in two-dimensional case it could be stopped by purely kinematic anticorrelation mechanism. In both situations the statistics of the field fluctuations demonstrates strong spatial and temporal intermittency on the growth stage.
