An objective vortex identification method
Yifei Yu, Yiqian Wang, Chaoqun Liu
Generally, the vortex structures should be independent of the observers who are moving, especially when their coordinates are non-inertial, which may result in confusions in commun…

Liutex-based Modified Navier-Stokes Equation
Yifei Yu, Jianming Liu, Yonghua Yan +3
The Navier-Stokes (NS) partial differential equations, as the governing equation of fluid dynamics, are based on particles with zero volume. In such a condition, conservation law o…

Physical meaning of vorticity based on the RS decomposition and an explicit formula for the Liutex vector
Yiqian Wang, Yisheng Gao, Chaoqun Liu
In the present study, the physical meaning of vorticity is revisited based on the RS decomposition proposed by Liu et al. in the framework of Liutex (previously named Rortex), a vo…
