The intrinsic decomposition of vorticity dynamics on an arbitrarily moving and deforming boundary
Tao Chen
Boundary vorticity dynamics provides a rigorous theoretical foundation for understanding vorticity creation at boundaries, vorticity-boundary interactions, as well as the rational…
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…
Vorticity-dynamical analysis of Richtmyer-Meshkov instability based on orbital-spin vorticity decomposition
Xi Chen, Tao Chen, Tianshu Liu
The present study provides a detailed vorticity-dynamical analysis of shock-driven hydrodynamic physics in canonical Richtmyer-Meshkov instability (RMI) flows: shock interaction wi…
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…
