内容摘要:

In this work, we develop a comprehensive study on the numerical approaches for a hemivariational inequality of stationary coupled Navier-Stokes/Navier-Stokes equations. The nonsmooth and nonconvex slip interface condition of friction-type is proposed to model geophysical flows, such as the atmosphere-ocean interaction. First, solution existence and uniqueness are explored. Second, a domain decomposition algorithm is proposed to decouple the system. Last, we obtain the error estimates of the finite element approximation. Numerical results are reported to illustrate the optimal convergence order predicted by the error analysis.
