Boundary vorticity dynamics of two-phase viscous flow
Tao Chen, Tianshu Liu
From the Navier-Stokes-Korteweg (NSK) equations, the exact relations between the fundamental surface physical quantities for two-phase viscous flow with diffuse interface are deriv…
Correspondences among CFTs with different W-algebra symmetry
Thomas Creutzig, Naoki Genra, Yasuaki Hikida +1
W-algebras are constructed via quantum Hamiltonian reduction associated with a Lie algebra and an -embedding into . We derive corresp…
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…
Optical-flow-based background-oriented schlieren technique for measuring a laser-induced underwater shock wave
Keisuke Hayasaka, Yoshiyuki Tagawa, Tianshu Liu +1
The background-oriented schlieren (BOS) technique with the physics-based optical flow method (OF-BOS) is developed for measuring the pressure field of a laser-induced underwater sh…
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…
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…
