  • Abstract

In this paper, the $\theta$ scheme of operator splitting methods is applied to the Navier-Stokes equations with nonlinear slip boundary conditions whose variational formulation is the variational inequality of the second kind with the Navier-Stokes operator. Firstly, we introduce the multiplier such that the variational inequality is equivalent to the variational identity. Subsequently, we give the $\theta$ scheme to compute the variational identity and consider the finite element approximation of the $\theta$ scheme. The stability and convergence of the $\theta$ scheme are showed. Finally, we give the numerical results.
