Six core issues for vortex definition and identification concern with (1) the absolute strength,(2) the relative strength,(3) the rotational axis,(4) the vortex core center,(5) the vortex core size,and (6) the vortex boundary (Liu C.2019).H......

A new vortex identification method (Liu et al.2016) was proposed to represent the rotation relative strength and capture and visualize the vortices in our previous study.The basic idea of the Ω method is that a ratio of the vorticity squar......
Explicit formula for the Liutex vector and physical meaning of vorticity based on the Liutex-Shear d

In the present study,the physical meaning of vorticity is revisited based on the Liutex-Shear (RS) decomposition proposed by Liu et al.in the framework of Liutex (previously called Rortex),a vortex vector field with information of both rota......
