Physics-informed data based neural networks for two-dimensional turbulence
Vijay Kag, Kannabiran Seshasayanan, Venkatesh Gopinath
Turbulence remains a problem that is yet to be fully understood, with experimental and numerical studies aiming to fully characterise the statistical properties of turbulent flows.…
Symmetry breaking in a turbulent environment
Alexandros Alexakis, François Pétrélis, Santiago J. Benavides +1
In this work we investigate symmetry breaking in the presence of a turbulent environment. The transition from a symmetric state to a symmetry-breaking state is demonstrated using t…
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…
Surface gravity waves propagating in a rotating frame: the Ekman-Stokes instability
Kannabiran Seshasayanan, Basile Gallet
We report on an instability arising when surface gravity waves propagate in a rotating frame. The Stokes drift associated to the uniform wave field, together with global rotation,…
Transitions between turbulent states in a two-dimensional shear flow
Vassilios Dallas, Kannabiran Seshasayanan, Stephan Fauve
We study the bifurcations of the large scale jets in the turbulent regime of a forced shear flow using direct numerical simulations of the Navier-Stokes equations. The bifurcations…
Dynamo saturation down to vanishing viscosity: strong-field and inertial scaling regimes
Kannabiran Seshasayanan, Basile Gallet
We present analytical examples of fluid dynamos that saturate through the action of the Coriolis and inertial terms of the Navier-Stokes equation. The flow is driven by a body forc…
