Large-Eddy simulation of rim seal ingestion

, 2020
Unsteady flow dynamics in turbine rim seals are known to be complex and attempts accurately to predict the interaction of the mainstream flow with the secondary air system cooling flows using computational fluid dynamics (CFD) with Reynolds-averaged ...

A Comparison of Single and Double Lip Rim Seal Geometries [PDF]

, 2017
The effect of the purge flow, engine-like blade pressure field, and mainstream flow coefficient are studied experimentally for a single and double lip rim seal.

Influence of slip on the Rayleigh-Plateau rim instability in dewetting viscous films [PDF]

, 2013
A dewetting viscous film develops a characteristic fluid rim at its receding edge due to mass conservation. In the course of the dewetting process, the rim becomes unstable via an instability of Rayleigh-Plateau type.

LARGE-EDDY SIMULATION OF RIM SEAL INGESTION

, 2010
Unsteady flow dynamics in turbine rim seals are known to be complex and attempts accurately to predict the interaction of the mainstream flow with the secondary air system cooling flows using CFD with RANS turbulence models have proved difficult.

Design of an improved turbine rim-seal [PDF]

, 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 life of highly stressed ...

Short Note: Report of mummified leopard seal carcass in the southern Dry Valleys, McMurdo Sound, Antarctica. [PDF]

, 2010
The wide spread occurrence of mummified seal and penguin carcasses tens of kilometres from the open ocean is an interesting phenomenon occurring in the Antarctic Dry Valleys.

A Rim seal ingress model based on turbulent transport

, 2017
Copyright © 2017 ASME. Recent experimental work from the present authors demonstrated that interactions between the mainstream and cavity/rim seal flows lead to ingestion mechanisms with a range of length scales. In addition to the (well known) effect of

Assessing grey seal (Halichoerus grypus) diet in western Scotland [PDF]

, 2008
Grey seal diet was last comprehensively studied in western Scotland in 1985. Since then, the grey seal population has increased by approximately 30% and relative abundance of fish stocks in the area has changed markedly.

Inertial waves in turbine rim seal flows [PDF]

, 2020
Rotating fluids are well-known to be susceptible to waves. This has received much attention from the geophysics, oceanographic and atmospheric research communities.
