Minimal model of quasi-cyclic behaviour in turbulence driven by Taylor--Green forcing
Ryo Araki, Wouter J. T. Bos, Susumu Goto
We attempt to formulate the simplest possible model mimicking turbulent dynamics, such as quasi-cyclic behaviour (QCB), using only three variables. To this end, we first conduct di…
Self-similar hierarchy of coherent tubular vortices in turbulence
Tomonori Tsuruhashi, Susumu Goto, Sunao Oka +1
Energy transfers from larger to smaller scales in turbulence. This energy cascade is a process of the creation of smaller-scale coherent vortices by larger ones. In our recent stud…
Mathematical reformulation of the Kolmogorov-Richardson energy cascade in terms of vortex stretching
Tsuyoshi Yoneda, Susumu Goto, Tomonori Tsuruhashi
In this paper, with the aid of direct numerical simulations (DNS) of forced turbulence in a periodic domain, we mathematically reformulate the Kolmogorov-Richardson energy cascade…
