Small-scale dynamo with nonzero correlation time
Kishore Gopalakrishnan, Nishant K Singh
The small-scale dynamo is typically studied by assuming that the correlation time of the velocity field is zero. Some authors have used a smooth renovating flow model to study how…
Mean-field dynamo due to spatiotemporal fluctuations of the turbulent kinetic energy
Kishore Gopalakrishnan, Nishant Singh
In systems where the standard effect is inoperative, one often explains the existence of mean magnetic fields by invoking the `incoherent effect', which appeals to fluctuat…
Magnetic helicity fluxes from triple correlators
Kishore Gopalakrishnan, Kandaswamy Subramanian
Fluxes of the magnetic helicity density play an important role in large-scale turbulent dynamos, allowing the growth of large-scale magnetic fields while overcoming catastrophic qu…
Shell model for stratified convection: implications for the solar convective conundrum
Kishore Gopalakrishnan, Nishant K. Singh
We extend the notion of a shell model to stratified systems, and propose one that represents stratified, nonmagnetic, nonrotating convection at low Mach number. Motivated by profil…
