Numerical Analysis of Flow across Brush Elements Based on a 2-D Staggered Tube Banks Model
Aerospace, 2021 In order to improve efficiency in turbomachinery, brush seal replaces labyrinth seals widely in the secondary air system. A 2-d staggered tube bank model is adopted to simulate the gas states and the pressure character in brush seal, and computational ...

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.

Design of magnetic brush composite seal [PDF]
EPJ Web of ConferencesBrush seal is a mechanical sealing method that achieves sealing by the relative high-speed friction between brushes and the sealed object. It is a non-contact sealing method that overcomes some of the disadvantages of traditional mechanical seals in ...

Leakage performance predictions of a brush seal based on fluid–solid coupling method
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 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 ...
