Arthroscopic Repair of Labrum Using the Inverted V-Shape Double-Strand Vertical Mattress Suture Technique in Hip Joint. [PDF]
Arthrosc TechAbstract The labral suture is essential in the arthroscopic treatment of hip acetabular labral injuries and maintains its suction sealing effect. The traditional single‐strand loop fixation, with its loop around the labrum tissue, may cause labral eversion and disrupt the sealing effect.

Computational and Experimental Assessment of Rim Sealing Flows in Axial Turbine Chute Rim Seals
AIAA Propulsion and Energy 2021 Forum, 2021 Computations were performed with a URANS model and a novel LES code including near wall boundary layer modelling, the wall-modelled LES (WMLES). The experimental data was obtained in the Oxford Rotor Facility (ORF). The main focus of this study was the mean cavity flow aerodynamics and the sealing performance of the chute seal under a range of ...

Unsteady Flow Phenomena in Turbine Rim Seals [PDF]
Volume 5A: Heat Transfer, 2016 While turbine rim sealing flows are an important aspect of turbomachinery design, affecting turbine aerodynamic performance and turbine disc temperatures, the present understanding and predictive capability for such flows is limited. The aim of the present study is to clarify the flow physics involved in rim sealing flows and to provide high quality ...

Sealing Performance of a Turbine Rim Chute Seal Under Rotationally-Induced Ingestion
Journal of Physics: Conference Series, 2021 Abstract This study focuses on the sealing capability of a turbine rim seal subject to hot gas ingestion driven purely by the rotor disc pumping effect rather than that induced by mainstream features such as vane and rotor blade passing. The aim is to provide useful data for conditions in which rotation dominates, and to clarify the flow
