On the thermal behaviour of gas turbine filament seals

Abstract:

Advanced rotating shaft seals have the potential to significantly increase the efficiency and performance of steam and gas turbines. Two such seals, brush and leaf seals, rely on the use of thousands of flexible filaments to close clearances between rotating components and their static casings. The current life of the components is poor compared to the rest of the gas turbine, limiting the seals’ deployment, particularly in the jet engine at high temperature and pressure. Poor understandin...
