Investigation of correlation between vorticity, Q, λci, λ2, Δ and Liutex

Y Yu, P Shrestha, O Alvarez, C Nottage, C Liu - Computers & Fluids, 2021 - Elsevier
For a long time, people hold an idea that vorticity is equivalent to vortex for fluid flow since
vorticity represents rotation for rigid body. Nevertheless, many experimental results do not …
