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…
