Brush seal with thermo-regulating bimetal elements
Open Engineering, 2018 This paper presents a new brush seal construction idea. It was shown that it is possible to use bimetallic elements for the construction of the brush seal, which have a thermoregulatory function by relieving a contact area between bristles and a shaft ...

Brush Seal Performance and Durability Issues Based on T-700 Engine Test Results
International Journal of Rotating Machinery, 1995 The integrity and performance of brush seals have been established. Severe bench and engine tests have shown high initial wear or rub-in rates, material smearing at the interface, and bristle and rub-runner wear, but the brush seals did not fail.

Analysis of Brush Seal Interaction with Steam Turbine Rotor-Shafts
Science, Engineering and TechnologyHigh-speed turbines are a major source for power production. They utilize high pressure and temperature fluid flow. Sealing of these machines to decrease the flow losses has been a major engineering challenge since the inception of steam turbines.

Contact Force Analysis of a Rotor-Brush Seal System With Eccentricity and Airflow
IEEE Access, 2019 The mechanics properties of brush seals are usually very complicated. Here, the contact force of a rotor-brush seal system was analyzed based on the bending deformation theory considering the interaction of eccentricity and flow induced force.
