Effects of radial conductivity variation on the Ponomarenko dynamo
Shipra Verma, Kannabiran Seshasayanan
We study the effects of conductivity variation on the Ponomarenko dynamo. Taking monotonically increasing/decreasing and sinusoidally varying radial profiles, we study the kinemati…
Large small-scale kinematic dynamo in protoneutron stars
Shipra Verma, Kannabiran Seshasayanan, Raphaël Raynaud +1
Magnetars are young, isolated neutron stars that possess an exceptionally strong magnetic field, with surface dipolar strengths on the order of G. One of the plausible sc…
Relaxation and statistical equilibria in generalised two-dimensional flows
Vibhuti Bhushan Jha, Kannabiran Seshasayanan, Vassilios Dallas
We study relaxation toward statistical equilibrium states of inviscid generalised two-dimensional flows, where the generalised vorticity is related to the streamfunction vi…
Nonequilibrium Continuous Transition in a Fast Rotating Turbulence
Chandra Shekhar Lohani, Suraj Kumar Nayak, Kannabiran Seshasayanan +1
We study the saturation of three-dimensional unstable perturbations on a fast rotating turbulent flow using direct numerical simulations (DNSs). Under the effect of Kolmogorov forc…
Cascades transition in generalised two-dimensional turbulence
Vibhuti Bhushan Jha, Kannabiran Seshasayanan, Vassilios Dallas
Generalised two-dimensional (2D) fluid dynamics is characterised by a relationship between a scalar field , called generalised vorticity, and the stream function , namely $q…
Effect of confinement on the transition from 2D to 3D fast rotating flows
Chandra Shekhar Lohani, Suraj Kumar Nayak, Kannabiran Seshasayanan
We study the effect of confinement on the three-dimensional linear instability of fastly rotating two-dimensional turbulent flows. Using the large scale friction to model the effec…
