Design of an improved turbine rim-seal
James A. Scobie, Roy Teuber, Yan Sheng Li, Carl M. Sangan, Michael Wilson, Gary D. Lock
Feb 28, 2016
Rim seals are fitted in gas turbines at the periphery of the wheel-space formed between rotor disks and their adjacent casings. These seals, also called platform overlap seals, reduce the ingress of hot gases which can limit the...

Influence of Flow Coefficient on Ingress Through Turbine Rim Seals
Rim seals are critical in terms of limiting the temperature of highly-stressed engine components but function with a penalty to the power output and contribute to entropy gain stemming from mixing losses in the turbine. Ingress...

Jan 01, 2019
In high-pressure turbines, cool air is purged through rim seals at the periphery of wheel-spaces between the stator and rotor disks. The purge suppresses the ingress of hot gas from the annulus but superfluous use is...

A contrasting function for miR-137 in embryonic mammogenesis and adult breast carcinogenesis
Jong Min Lee, Kyoung Won Cho, Eun Jung Kim, Qinghuang Tang, Kye Seong Kim, Cheryll Tickle, Han Sung Jung
Sep 01, 2015
MicroRNAs are differentially expressed in breast cancer cells and have been implicated in cancer formation, tumour invasion and metastasis. We investigated the miRNA expression profiles in the developing mammary gland....
Use of pressure measurements to determine effectiveness of turbine rim seals
The ingress of hot gas through the rim seal of a gas turbine depends on the pressure difference between the mainstream flow in the turbine annulus and that in the wheel-space radially inward of the rim seal. In this paper, a...
