The flow is described by the compressible unsteady Navier-Stokes equations using the Arbitrary Lagrangian-Eulerian (ALE) method. The governing equations are discretized in space by the discontinuous Galerkin finite element method (DGFEM). The results for flow in a channel with a prescribed periodic motion of a part of the channel walls oscillating with the frequency 100 Hz. The results are compared with the results computed by the finite method.
