Brush seals and common issues in brush seal applications [PDF]
, 2012 Brush seals are receiving wider acceptance with growing number of successful turbomachinery sealing applications over the past couple of decades. Due to their complaint nature these seals can recover from large transient rotor interference occurrences without any appreciable sustained damage or permanent performance loss. They are formed by a multitude

Evaluation of Brush Seal Performance for Oil Sealing Applications
39th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2003Oil 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 applications further complicate the problem.

Brush Seal Temperature Distribution Analysis
Journal of Engineering for Gas Turbines and Power, 2005Brush 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. Considering large surface area and accelerated oxidation rates, frictional heat at bristle tips is another major concern especially in

Multiple Brush Seals in Series
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 1997Rolls-Royce has identified phenomena associated with aeroelastic instability of brush seal bristles, when multiple seals are operated in series at high pressure loading. This paper gives a general overview of test experience to date. A brush seal test facility commissioned by Rolls-Royce at Oxford University is described, along with results from double
