Three-Dimensional Dynamic Labyrinth Seal Analysis.

Abstract

A transient capability has been developed for fluid flow analysis in a labyrinth seal configuration with a whirling rotor. The technique utilizes a moving coordinate system that allows transient calculations of the flow and pressure fields. Two sample calculations with different rotor oscillation displacements are presented and the results demonstrate the potential of this analysis.
