Finger seals represent a compliant seal configuration. What differentiates and makes them
preferable to the brush seals is their potential hydrodynamic lifting capabilities, and thus …

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 …

The flow behavior through a brush seal has been investigated by developing a flow analysis
procedure with a porous medium approach. In order to increase the brush seal performance …

Fibers such as fabric and bristles can be readily fabricated into a variety of seal
configurations that are compliant and responsive to high speed or lightly loaded systems. A …

The leakage performance of a brush seal with gaseous working fluids at static and low rotor
speed conditions was investigated. This report includes the leakage results for air, helium …

The industrial applications of brush seals have been increasing due to their superior sealing
performance. Advances in the understanding of seal behavior have been pushing the …

Brush seals have established a niche in the gas-to-gas sealing against leakage in modern
turbine engines. The variable nature of the brush during operation makes leakage prediction …

We investigate non-contact finger seal owing to its potential to reduce the specific fuel
consumption of a gas turbine engine by 2–3%. The compliance features combined with the …

The technology of shaft compliant seals was revolutionized when brush seals first replaced
the labyrinth seals at many locations along compressor and turbine shafts. Finger seals …

The work presented here concerns the numerical development and simulation of the flow,
pressure patterns, and motion of a pair of fingers arranged one behind the other and axially …
