Investigation of brush seal flow characteristics using bulk porous medium approach (Conference Paper)
(2003)
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 and use at more severe operating conditions, ...
Evaluation of brush seal performance for oil sealing applications
(2003)
Oil sealing at high speeds is one of the major problems engineers should address in turbomachinery design. High temperatures faced in oil sumps in aircraft engines, and large seal sizes typical in land based turbine ...
Brush seal temperature distribution analysis (Conference Paper)
(2005)
Brush seals are designed to survive transient rotor rubs. Inherent brush seal flexibility reduces frictional heat generation. However, high surface speeds combined with thin rotor sections may result in local hot spots. ...
Oil temperature analysis of brush seals
(2008)
Due to their superior performance and stable leakage characteristics, brush seals are one of the dynamic seals used in oil and oil mist applications in aero-engines and turbines. The viscous medium between the high speed ...
A simple FEM model for foil bearings under differential pressure
(2010)
A bump-type foil bearing consists of a compliant corrugated sheet metal supporting structure that is covered by a thin top foil surface. Bumps serve as stiffener and damping elements to increase the stability of the system ...
An investigation of pressure stiffness coupling in brush seals
(2006)
In recent years, brush seals found common use in turbomachinery applications. There are a number of seal locations on gas turbines that have significant performance derivatives. These include the compressor discharge, ...
Effect of shear heat on hydrodynamic lift of brush seals in oil sealing
(2006)
Due to their superior performance and stable leakage characteristics, brush seals are one of the dynamic seals used in oil and oil mist applications in aero-engines and turbines. The viscous medium between the high speed ...
