Leakage performance predictions of a brush seal based on fluid–solid coupling method [PDF]
Science Progress, 2020 The sealing performance of a brush seal is studied in this article. At present, the mostly used model to analyze the performance of a brush seal is porous medium model in which the effect of bristle deformation is not considered.

Brush seal contact force theory and correlation with tests
AEJ - Alexandria Engineering Journal, 2022 Brush seals are leakage performance systems that are operating against turbine shafts and bucket tips. Flexible bristle structure can compensate the rotor interference during transients, which enables closer clearance control in turbine and turbo-engine ...

Wear and Leakage Behaviors of Brush Seal Considering Eccentricity and Radial Deformation
Energies, 2023 Brush seals can improve engine performance by reducing leakage. Wear models of brush seals provide methods to predict wear and leakage. However, rotor eccentricity, radial deformation, and hysteresis effect of bristles are not considered systematically ...

International Journal of Rotating Machinery, 2002 The proven technology of brush seals has been extended to the mitigation of problems arising from friction and wear at the bristle-rotor interface at high surface speeds. In prototype testing, the brush is mounted on, and free to rotate with the shaft, thus providing a compliant primary seal.
