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.

Sealing performance prediction software
Sealing Technology, 1997Abstract Elastomer seals are widely used throughout industry and seal failure can be very expensive, in both financial and safety terms. One failure mode causing major concern is progressive degradation. It is generally of a long term nature and its extent and consequences in service can be particularly difficult to predict.

Materials Testing, 1997
In this article, the author discusses the importance of selecting the proper materials for various seal designs. For every seal application there is an optimal pair of rubbing materials that provides the longest life and lowest operating cost. This rubbing pair must be selected from among scores of seal nose materials and an equally large number of ...

Seal Performance Analysis of Hard Seal Ceramic Ball Valve
2018 IEEE International Conference on Mechatronics and Automation (ICMA), 2018Due to high temperature, high pressure, strong corrosion and other adverse conditions, metal valves can easily cause seal failure and leak in coal chemical, petrochemical and other industries. This article mainly aims at the problem that the Ceramic ball valve is prone to seal failure, and expands research to the leakage of the valve.

Sealing Performance of a Magnetic Fluid Seal for Rotary Blood Pumps
Artificial Organs, 2009AbstractA magnetic fluid (MF) for a rotary blood pump seal enables mechanical contact‐free rotation of the shaft and, hence, has excellent durability. The performance of a MF seal, however, has been reported to decrease in liquids. We have developed a MF seal that has a “shield” mechanism and a new MF with a higher magnetization of 47.9 kA/m.

Seal Leakage Performance Characterization
A S L E Transactions, 1977The use of the “flow resistance” concept in the sealing context is discussed. A number of model seal configurations are dealt with in detail, leading to the expressions for flow resistance. It is pointed out that flow resistance for seals parallels the load capacity of bearings as a quantitative measure of performance and it is concluded that, although

Seal/Groove Performance Analysis Models
SAE Technical Paper Series, 2002<div class="htmlview paragraph">Maximum fluid displacement and drag are among the major performance requirements in a brake caliper design. Among the factors that affect displacement and drag, the seal-groove provides the cheapest design option for modifying the caliper performance.
