We investigated fluid flow over chemically patterned surfaces. Our findings show the Navier slip boundary condition accurately describes flow locally, validating its use in hydrodynamic models for complex surfaces.

Area of Science:

  • Fluid dynamics
  • Surface science
  • Computational physics

Background:

  • Chemically patterned surfaces create complex fluid-structure interactions.
  • Understanding boundary conditions is crucial for accurate flow modeling.

Purpose of the Study:

  • To investigate the validity of the Navier slip boundary condition for flows over chemically patterned surfaces.
  • To develop and validate a continuum hydrodynamic model for such flows.

Main Methods:

  • Molecular dynamics (MD) simulations were used to model fluid flow.
  • A subtraction scheme was developed to analyze local slip behavior.
  • A continuum hydrodynamic model incorporating a spatially varying slip length was formulated.

Main Results:

  • Fluid forces and stresses exhibit lateral variations along the patterned surface.
  • The Navier slip boundary condition was validated locally for the patterned surface.
  • Continuum model predictions showed quantitative agreement with MD simulation results.

Conclusions:

  • The Navier slip boundary condition is applicable locally on chemically patterned surfaces.
  • Continuum hydrodynamic models with spatially varying slip lengths can accurately predict flow behavior.
