Quadruple decomposition of boundary vorticity flux
Tao Chen, Tianshu Liu
First introduced by Lighthill in 1963 for two-dimensional flows and later generalized by Jie-Zhi Wu to three-dimensional scenarios since 1986, the boundary vorticity flux (BVF) is…

A general kinematic theory of fluid-element rotation and intrinsic vorticity decompositions
Tao Chen, Jie-Zhi Wu, Feng Mao +1
The present study proposes a general kinematic theory for fluid-element rotation and intrinsic vorticity decompositions within the context of vorticity and vortex dynamics. Both th…

Physical structures of boundary fluxes of orbital rotation and spin for incompressible viscous flow
Tao Chen
Vorticity is locally created on a boundary at the rate measured by the boundary vorticity flux, which can be further decomposed as the sum of the orbital rotation and the (generali…
