Mean field dynamo action in shearing flows. II: fluctuating kinetic helicity with zero mean
Naveen Jingade, Nishant K. Singh
Here we explore the role of temporal fluctuations in kinetic helicity on the generation of large-scale magnetic fields in presence of a background linear shear flow. Key techniques…

Mean field dynamo action in shear flows. I: fixed kinetic helicity
Naveen Jingade, Nishant K. Singh
We study mean-field dynamo action in a background linear shear flow by employing pulsed renewing flows with fixed kinetic helicity and nonzero correlation time (). We use plane…

Generation of large-scale magnetic fields due to fluctuating in shearing systems
Naveen Jingade, Nishant K. Singh, S. Sridhar
We explore the growth of large-scale magnetic fields in a shear flow, due to helicity fluctuations with a finite correlation time, through a study of the Kraichnan-Moffatt model of…
