The paper presents the results of a numerical and experimental investigations of the steady and unsteady flow field in a low speed axial flow compressor stage with the use of the three systems, based on the quite different measurement principles. The measurements in the compressor stage were supported and compared with unsteady three-dimensional computational fluid dynamic calculations. Comparison of the CFD and experimental results showed reasonable agreement in the working points of the overall performance characteristic of the stage.
