Vortex Core and POD Analysis on Hairpin Vortex Formation in Flow Transition
Sita Charkrit, Chaoqun Liu
In this study, the new concept of vortex core line based on Liutex definition is applied to demonstrate that vortex ring is not part of the Lambda-vortex and the generation of ring…
Letter: Modified normalized Rortex/vortex identification method
Jianming Liu, Chaoqun Liu
In this paper, a modified normalized Rortex/vortex identification method named Omega_R is presented to improve the original Omega_R method and cure the bulging phenomenon on the is…
Letter: Mathematical Foundation of Turbulence Generation-Symmetric to Asymmetric Liutex/Rortex
Jian-ming Liu, Yue Deng, Yi-sheng Gao +2
Vortex has been considered as the building block and muscle of turbulence for long time. A new physical quantity called Liutex (previously named Rortex) has been defined as the rig…
A Liutex based definition of vortex axis line
Chaoqun Liu, Yi-sheng Gao, Jian-ming Liu +1
Eulerian local region-type vortex identification criteria, including the criterion, the criterion and the criterion et al., are widely used for vortex identification due to the sim…
