"We attempt to model a 2D rough surface by computing non-stationary Navier-Stokes flow over a periodic pattern. The solution is obtained by means of finite element method (FEM). We use non-conforming Crouzeix Raviart elements for velocity and piecewise constant elements for pressure. The resulting linear system is solved by multigrid method. We present computational studies of the problem."@en . "Flow over a rough surface" . "Flow over a rough surface"@en . "Praha" . . "Nov\u00E9 Hrady" . . . "2010-01-18+01:00"^^ . "4"^^ . .
