Modelling and synthesizing turbulence with multi-scale coherent vortices
Zishuo Han, Weiyu Shen, Yue Yang
Turbulence is a complex system exhibiting both universal statistical features and prominent coherent structures. We model turbulence using coherent vortices distributed within a mu…

Constructing wall turbulence using hierarchical hairpin vortices
Weiyu Shen, Yuchen Ge, Zishuo Han +2
Wall-bounded turbulence is characterized by coherent, worm-like structures such as hairpin vortices. The attached-eddy model provides a successful statistical framework for the log…

Vortex-magnetic competition and regime transitions in antiparallel flux tubes
Weiyu Shen, Rodolfo Ostilla-Mónico, Xiaojue Zhu
Vortex-magnetic interactions shape magnetohydrodynamic (MHD) turbulence, influencing energy transfer in astrophysical, geophysical, and industrial systems. On the Sun, granular-sca…
