Porosity Modeling of Brush Seals

Journal of Tribology, 1997
A new model for predicting leakage flows through the bristle pack of brush seals is developed. In the model, the bristle pack is treated as a porous medium. Good agreement is demonstrated between predictions from a one-dimensional form of the model and a wide range of experimental data available from the literature, for seals with a bristle pack to ...

Rotating Brush Seal

50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2014
A brush seal for use between a rotating component and a stationary component in a turbomachine is disclosed. The brush seal according to embodiments of this invention includes a set of bristles having a fixed end and a free end, wherein the fixed end is attached to the rotating component with a mechanical clamping element and the free end extends ...

Insights Into Frictional Brush Seal Hysteresis

Volume 7B: Heat Transfer — General Interest/Additive Manufacturing Impacts on Heat Transfer; Internal Air Systems; Internal Cooling, 2023
Abstract Brush seals offer a superior sealing effectiveness compared to labyrinth seals. However, widespread use of brush seals is constrained by deleterious behaviors such as pressure-stiffening and hysteresis. For the latter, the bristles bend during the shaft incursion process and do not fully recover during the shaft retraction ...

Brush Seal Hysteresis

48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference &amp; Exhibit, 2012
The use of Brush Seals continues to expand in both the Power Generation and the Aerospace markets and we continue to learn more about their functionality. This paper continues on from our previous papers and in particular AIAA 2002-3794 which examines, analytically and experimentally the effects of Hysteresis.
