A variational approach to the moving contact line hydrodynamics
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
In immiscible two-phase flows, contact line denotes the intersection of the fluid-fluid interface with the solid wall. When one fluid displaces the other, the contact line moves al…
Molecular hydrodynamics of the moving contact line in two-phase immiscible flows
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
The ``no-slip'' boundary condition, i.e., zero fluid velocity relative to the solid at the fluid-solid interface, has been very successful in describing many macroscopic flows. A p…
Liquid crystal pretilt control by inhomogeneous surfaces
Jones T. K. Wan, Ophelia K. C. Tsui, Hoi-Sing Kwok +1
We consider the pretilt alignment of nematic liquid crystal (LC) on inhomogeneous surface patterns comprising patches of homeotropic or homogeneous alignment domains, with azimutha…
Hydrodynamic slip boundary condition at chemically patterned surfaces: A continuum deduction from molecular dynamics
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
We investigate the slip boundary condition for single-phase flow past a chemically patterned surface. Molecular dynamics (MD) simulations show that modulation of fluid-solid intera…
Molecular scale contact line hydrodynamics of immiscible flows
Tiezheng Qian, Xiao-Ping Wang, Ping Sheng
From extensive molecular dynamics simulations on immiscible two-phase flows, we find the relative slipping between the fluids and the solid wall everywhere to follow the generalize…
