A Parametric Study on the Aeroelastic Stability of Rotor Seals

Labyrinth seals are widely used in rotating machinery and can be prone to aeroelastic instabilities. The rapid development of computational fluid dynamics now provides a hight fidelity approach for predicting the aeroelastic behaviour of labyrinth seals in theres dimension and exhibits great potential within industrial application, especially during the detailed design stages. In the current publication a time marching unsteady Reynolds-averaged Navier-Stokes solver was employed to study the various historically identified parameters that have essentially influence on the stability of labyrinth seals
