Experimental Study on the Wear-in Behaviour of Brush Seals

Hildebrandt, Manuel; Schwitzke, Corina; Bauer, Hans-Jörg


Abstract (englisch):
Although some investigations on the wear behaviour of
brush seals can be found in the literature, not all aspects are yet
understood during the wear-in process of the seal in operation.
However, it is important to understand all aspects in order to en-
sure a long service life of the seal. The present paper gives an
overview of the procedure, the results and the knowledge gained
through the long-term rub tests carried out with a tungsten car-
bide coated rotor with the aim of determining the time required to
wear the seal in (”time-on-condition”). The total test duration
