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…
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…
Two-dimensional Rayleigh-Bénard convection without boundaries
Philip Winchester, Vassilios Dallas, Peter D. Howell
We study the effects of Prandtl number and Rayleigh number in two-dimensional Rayleigh-Bénard convection without boundaries, i.e. with periodic boundary conditions. In th…
The onset of zonal modes in two-dimensional Rayleigh-Bénard convection
Philip Winchester, Peter D. Howell, Vassilios Dallas
We study the stability of steady convection rolls in 2D Rayleigh--Bénard convection with free-slip boundaries and horizontal periodicity over twelve orders of magnitude in the Pran…
Zonal flow reversals in two-dimensional Rayleigh-Bénard convection
Philip Winchester, Vassilios Dallas, Peter D. Howell
We analyse the nonlinear dynamics of the large scale flow in Rayleigh-Bénard convection in a two-dimensional, rectangular geometry of aspect ratio . We impose periodic and free-…
Bifurcations of a plane parallel flow with Kolmogorov forcing
Kannabiran Seshasayanan, Vassilios Dallas, Stephan Fauve
We study the primary bifurcations of a two-dimensional Kolmogorov flow in a channel subject to boundary conditions chosen to mimic a parallel flow, i.e. periodic and free-slip boun…
