Slip viscosity and strain-rate viscosity in Taylor-Couette laminar flows: Experimental falsification and end-wall effects
Jian He, Jin Wang, Qiaocong Kong +4
The viscous force should be shear force, the difference between the strain-rate viscosity and the slip viscosity is that the former has conjugate shear force, while the latter does…

No vortex in straight flows -- on the eigen-representations of velocity gradient
Xiangyang Xu, Zhiwen Xu, Changxin Tang +2
Velocity gradient is the basis of many vortex recognition methods, such as Q criterion, criterion, criterion, criterion and criterion, etc.. Except the $λ_…
