MacCormack scheme and Jameson artificial viscosity are used for numerical solution in the form of finite volume method with grid of quadrilateral cells. Mathematical model is unsteady system of 2D laminar Navier-Stokes equations. Unsteady behavior is caused by time dependent boundary of lower. The channel represents a simple case of vokal tract. An unsteady domain is presented using Arbitrary Lagrangian-Eulerian method. In the work several numerical results of flows in two different channels are presented."@en . . "4"^^ . . . "21220" .
