Generalized Navier Boundary Condition for the Moving Contact Line

  title={Generalized Navier Boundary Condition for the Moving Contact Line},
  author={Xiaoping Wang and Ping Sheng},
From molecular dynamics simulations on immiscible flows, we find the relative slipping between the fluids and the solid wall everywhere to follow the generalized Navier boundary condition, in which the amount of slipping is proportional to the sum of tangential viscous stress and the uncompensated Young stress. The latter arises from the deviation of the fluid-fluid interface from its static configuration. We give a continuum formulation of the immiscible flow hydrodynamics, comprising the… CONTINUE READING
