A self-induced mechanism of large-scale helical structures in compressible turbulent flows
Zheng Yan, Jianchun Wang, Lifeng Wang +6
A novel self-sustaining mechanism is proposed for large-scale helical structures in compressible turbulent flows. The existence of two channels of subgrid-scale and viscosity terms…

A quasi-dynamic one-equation model with joint constraints of kinetic energy and helicity fluxes for large eddy simulation of rotating turbulence
Depei Song, Changping Yu, Zheng Yan +1
For settling the problem with rotating turbulence modelling, a quasi-dynamic one-equation subgrid-scale (SGS) model is proposed in this paper. Considering the key role of the joint…

Dual channels of helicity cascade in turbulent flows
Zheng Yan, Xinliang Li, Changping Yu +1
Helicity, as one of only two inviscid invariants in three-dimensional turbulence, plays an important role in the generation and evolution of turbulence. From the traditional viewpo…
