Labyrinth Seal Air Flow Investigation and Measurement Device Introduction
M. Čížek, J. Pařez
Abstract:
For good aircraft gas turbine performance, a proper function of labyrinth seals sealing between rotating shaft and stator is necessary. This article presents comparison of mass flow through a labyrinth seal calculated using analytical solution and CFD. A new design of labyrinth seal measurement device is presented and its function is investigated using CFD.
Keywords:
labyrinth seal, mass flow, aircraft gas turbine, analytical and CFD calculation
