摘要
In this paper, we consider a two-grid quadratic equal-order stabilized method for the stationary incompressible Navier-Stokes equations with nonlinear slip boundary conditions. Our two-grid stabilized method consists of computing one nonlinear problem on a coarse mesh and then solving a linearization correction problem on a fine mesh. Moreover, the stability and convergence of the present method are derived. Finally, numerical experiments are performed to confirm our theoretical results. (C) 2018 Elsevier Inc. All rights reserved.
