In view of its combination of distinctive qualities, including strong tensile and tearing strength
along with exceptional dynamic capabilities, which make it a strategic and irreplaceable …

The overall efficiency of gas turbines is strongly affected by the performance of the sealing
arrangement between the stationary and rotary components. Maintaining an accurate …

A relatively simple theory is presented that can be used to model the flow and pressure
distribution in a brush seal matrix. The model assumes laminar, compressible, isothermal …

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 …

This paper discusses the question of heat flux distribution between bristle package and rotor
during a rubbing event. A three-dimensional Computational Fluid Dynamics (3D CFD) …

In this paper, an experimental program and a CFD based mathematical model using a brush
seal at two bristle to rotor clearances (0.27 mm and 0.75 mm) are presented. The …

A five times scale model of an engine brush seal has been manufactured. The bristle
stiffness and pressure were chosen to satisfy close similarity of the relevant non-dimensional …

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 …
