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...

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...

Nonverbal Auditory Cues Allow Relationship Quality to be Inferred During Conversations.
UNLABELLED: The claim that nonverbal cues provide more information than the linguistic content of a conversational exchange (the Mehrabian Conjecture) has been widely cited and equally widely disputed, mainly on methodological...
Nylon-11 nanowires for triboelectric energy harvesting
Triboelectric energy harvesting from ambient mechanical sources relies on motion-generated surface charge transfer between materials with different electron affinities. In order to achieve highly efficient energy harvesting...
