The Role of Helical and Non-Helical Drives on the evolution of Self-Consistent Dynamos
Shishir Biswas, Rajaraman Ganesh
In the self-consistent dynamo limit, the magnetic feedback on the velocity field is sufficiently strong to induce a change in the topology of the magnetic field. Consequently, the…

Effect of flow shear on the onset of dynamos
Shishir Biswas, Rajaraman Ganesh
Understanding the origin and structure of mean magnetic fields in astrophysical conditions is a major challenge. Shear flows often coexist in such astrophysical conditions and the…

Revisiting Kinematic Fast Dynamo in 3-dimensional magnetohydrodynamic plasmas: Dynamo transition from non-Helical to Helical flows
Shishir Biswas, Rajaraman Ganesh
Dynamos wherein magnetic field is produced from velocity fluctuations are fundamental to our understanding of several astrophysical and/or laboratory phenomena. Though fluid helici…
