Multiscale nonhelical dynamos



Description: 
In this talk a short introduction to the magnetic dynamo theory (explaining how magnetic fields can be produced by flows of an electrically conducting fluid) as well as recent advances made by the speaker and his collaborators will be presented. Generation of largescale magnetic field by zerohelicity flows will be discussed in detail using a rigorous mathematical approach (multiscale analysis). The following optimization problem will also be addressed  Which flow is the most favorable to magnetic field generation.
