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 v…

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…

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…
