We describe and compare two time-periodic flows embedded in large eddy simulation (LES) of turbulence in a three-dimensional, periodic domain subject to constant external forcing. One of these flows models the regeneration of large-scale structures that was observed in this geometry by Yasuda et al (2014 Fluid Dyn. Res. 46 061413), who used a smaller LES filter length and thus obtained a greater separation of scales of coherent motion. We speculate on the feasibility of modelling the…

Variational methods for finding periodic orbits in the incompressible Navier–Stokes equations
Abstract Unstable periodic orbits are believed to underpin the dynamics of turbulence, but by their nature are hard to find computationally. We present a family of methods to converge such unstable
Time-Periodic Inertial Range Dynamics.
TLDR
This work investigates scale-invariant dynamics through an unstable periodic orbit that coexists with turbulence of an incompressible fluid and yields a significant Kolmogorov energy spectrum.

Transitions in large eddy simulation of box turbulence
Abstract One promising decomposition of turbulent dynamics is that into building blocks such as equilibrium and periodic solutions and orbits connecting these. While the numerical approximation of

Unstable equilibrium solutions in a homogeneous shear flow with sinuous (streamwise-shift-reflection and spanwise-shift-rotation) symmetry are numerically found in large-eddy simulations (LES) with
Quasi-cyclic evolution of turbulence driven by a steady force in a periodic cube
The quasi-cyclic evolution of turbulence driven by a steady force in a periodic cube is investigated by means of large-eddy simulations with vanishing kinematic viscosity. By constraining the domain
