The presented paper concerns the steady and transient CFD analysis of the last stage of steam turbine 13K215. The aim of these studies is to investigate the flow instabilities and losses which appear in the flow. The studies were performed with the use of commercial software Ansys-CFX12. The FFT analysis was done which allows to calculate the amplitude and frequency of the main components. Additionally, on the basis of the steady analysis, the stage efficiency as well as the places of the losses generation were estimated.
