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…

Boundary sources of velocity gradient tensor and its invariants
Tao Chen, Jie-Zhi Wu, Tianshu Liu +1
The present work elucidates the boundary behaviors of the velocity gradient tensor () and its principal invariants () for compressible flow in…
