The flow is described by the unsteady Navier-Stokes equations (laminar) for the compressible fluid. The unsteady flow is caused by a prescribed time periodical motion of a part of the channel wall, which is changing the shape. The numerical solution is realized by the finite volume method and the explicit predictor-corrector MacCormack scheme with Jameson artificial viscosity using a grid of quadrilateral cells. The moved grid of quadrilateral cells is considered in the form of conservation laws using the Arbitrary Lagrangian-Eulerian method. Some numerical results of unsteady flows in a symmetric channel are presented for inlet Mach number M=0,02 , Reynolds number Re~1000 and for frequency of the wall motion 20 Hz. The numerical results were obtained using special software developed by the authors." . . "21220" .
