Abstrakt EN: This contribution is devoted to the numerical simulation of the transonic laminar fluid flow through the two-dimensional experimental cascade of symmetrical DCA8% profiles. For the numerical solution of the nonlinear conservative system of the compressible Navier-Stokes equations the cell-centred finite volume formulation of the explicit two-step MacCormack scheme with different TVD-type viscosity terms is used. The effects of different artificial viscosity terms on the laminar computation of the transonic flow through the experimental cascade are shown and the obtained results are compared in this paper. In order to validate our non-stationary results, another calculation with using the software package FLUENT was performed.
