Physical meaning of vorticity based on the RS decomposition and an explicit formula for the Liutex vector

27 Dec 2018 Wang Yiqian Gao Yisheng Liu Chaoqun

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 vortex vector field with information of both rotation axis and swirling strength [ C. Liu et al., "Rortex-A new vortex vector definition and vorticity tensor and vector decomposition", Phys. Fluids 30, 035103 (2018)]... (read more)
