Abstract
The verification of the computational models for unsteady flows through the oscillating blade row becomes more difficult, because the experimental data for three-dimensional flows are currently hardly available in the published literature. Therefore comparisons between numerical methods and experimental ones for simple cascade geometry at inviscid flow conditions must play an essential role in validation of the three-dimensional unsteady solution methods. In this study the numerical calculations were performed to compare the theoretical results with experiments for the harmonic motion. The calculations were carried out for the torsional and bending oscillations of the compressor cascade. The comparison of the calculated and experimental results for different conditions of the cascade oscillations has shown the good quantitative and qualitative agreement.
