Description	The aim of this article is to compare ans evaluate usability of the main state-of-the-art turbulence models in numerical simulations of a simple type of unsteady flow. The researched case is turbulent transonic flow over an oscillating NACA 0012 profile, which in its nature resembles a lot of effects with significant influence to the flow field (e.g. flutter). Mathematical model is described by the system of Reynolds-Averaged Navier-Stokes equation, which is solved using the finite volume method. The authors use two different schemes - an in-house developed solver (cell centered Modified Causon's scheme, which is based on MacCormack scheme in TVD form) and solver EDGE by the Swedish defence research agency FOI.
