Remarks on aerodynamic forces in seals of turbine stages

Abstract

This paper presents results of numerical examination of flow through over-shroud seals of turbine stages. Various labyrinth seals of different configurations and number of sealing teeth were considered. It was demonstrated that results of investigations of isolated seals cannot be directly used for analyzing turbine stage operation. Such approach may lead to relatively large errors in determining value of aerodynamic force and direction of its action.

Keywords:

rotor dynamics, self-excited vibrations, aerodynamic forces, blade seals, turbine shrouds
