Effect of Outer Fin Axial Gap on the Sealing Effectiveness and Fluid Dynamics of Radial Rim Seal
, 2017 The modern gas turbine is widely applied in the aviation propulsion and power generation. The rim seal is usually designed at the periphery of the wheel-space and prevented the hot gas ingestion in modern gas turbines.

Effects of Rotor Disc Growth on Flow and Heat Transfer Characteristics of Rim Seal
, 2017 Under actual operating conditions of gas turbine, centrifugal and thermal growth of disc in radial direction result in dislocation of inflow boundary at the disc mid-radius height, and a radial step of platform at high radius height.

Dynamic Contact Angle in Rim Instability of Dewetting Holes [PDF]
, 2006 The effects of dynamic contact angle (theta(d)), between a substrate and the melt of a dewetting polymer thin film, on the evolution of rim instabilities of dewetting holes were reported. Various theta(d)\u27s were achieved by covering SiOx surfaces with

Anti-Swirl Arrangements Prevent Rotor/Seal Instability
, 1989 Fluid involved in rotative motion (fluid “swirl”) within seals of high speed fluid handling machines is a recognized source of rotor instability. This type of instability leads to the limit cycle of rotor lateral precessional self-excited vibrations of a
