Title: 
Reversal of a large-scale flow in a randomly forced two-dimensional turbulence in a square domain

Abstract:
When a turbulent flow is somehow sustained in a closed container, a large-scale coherent flow often emerges. Moreover, in some situations, the direction of the large-scale flow changes randomly.
A numerical setting for such reversal phenomena in two-dimensional flow was proposed by Molenaar, Clercx and van Heijst (2004).
We numerically study the flow due to Molenaar et al. with emphasis on modeling the typical time scale between reversals.                   

We look forward to seeing many of you at the seminar.
