Abstract

In this paper the dynamic characteristics of rotating blades in axial-flow compressor by gas-structure interaction of various turbulence models were studied. Two-way order coupling algorithm of fluid-structure interaction was used to compute gas and rotating blades of compressor with CFX and ANSYS, the dynamics responses of blades in aerodynamic forces were obtained by iterative solving. A rotating blade flow channel model was established for fluid-structure interaction calculation, because of different turbulence models have great influence on simulate flow field, three turbulence models were used to discuss influence of coupling field on blades dynamic characteristic. The three turbulence models were standard κ-ε model, renormalization group κ-ε model and large eddy simulation model. In this paper the dynamic characteristics of blades in transient flow field with various turbulence models were obtained, a feasible method was provided for the engineering to estimate and research the performance characteristics of rotating blades in compressor.
