Navier slip boundary
WebEven though the Navier-slip boundary condition (1) has been widely accepted for computations of moving contact line problems, a general mathematical expression or an … WebThis paper reports the implementation of slip boundary conditions in the open-source computational library OpenFOAM. The linear and nonlinear Navier slip laws, which are newly implemented in this paper, can be used both for Newtonian and viscoelastic constitutive models.

WebThe upper boundary is a free boundary, and the lower boundary is a fixed boundary on which the Navier-slip boundary condition is imposed. [2] In both cases, Dirichlet or Navier-slip boundary conditions are considered. [3] This study aims to investigate the flow properties around a structure using Navier-slip boundary conditions.

WebThe sharp-interface limits of a phase-field model with a generalized Navier slip boundary condition for binary fluids with moving contact lines are studied by asymptotic analysis and numerical simulations. The effects of the mobility number as well as a phenomenological relaxation parameter on the boundary condition are considered.
