Abstract

The harmonic balance method which is included in STAR CCM+ code can simulate the whole unsteady flow at considerably reduced CPU costs. This paper represents 3D flow in turbine cascade in which the harmonic balance method is applied for modeling rotor – stator interaction and pressure fluctuations near trailing edges. Computational results are compared with experimental results which show importance of unsteady effects.
