  • Abstract

In this paper, we introduce a nonlocal model for linear steady Stokes system with physical no-slip boundary condition. We use the idea of volume constraint to enforce the no-slip boundary condition and prove that the nonlocal model is well-posed. We also show that and the solution of the nonlocal system converges to the solution of the original Stokes system as the nonlocality vanishes.

  • Keywords

Nonlocal Stokes system, nonlocal operators, smoothed particle hydrodynamics, incompressible flows, well-posedness, local limit.
