# Periodic orbits in large eddy simulation of box turbulence

@article{Veen2019PeriodicOI, title={Periodic orbits in large eddy simulation of box turbulence}, author={Lennaert van Veen and Alberto Vela-Mart{\'i}n and Genta Kawahara and Tatsuya Yasuda}, journal={Fluid Dynamics Research}, year={2019}, volume={51} }

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…
