eng Abstract:
We attempt to model a 2D rough surface by computing non-stationary Navier-Stokes ow over a periodic pattern. The solution is obtained by means of _nite element method (FEM). We use non-conforming Crouzeix Raviart elements for velocity and piecewise con- stant elements for pressure. The resulting linear system is solved by multigrid method. We present computational studies of the problem.
