Abstract: The numerical solution model of the labyrinth seal considering the multiple frequencies elliptical whirling of the rotor and swirl brake was established by the computational fluid dynamics (CFD) technique. Then, the dynamic ...

Abstract: Bristles in the first few rows float up from the rotor surface due to the radial airflow in the gap between the front plate and bristle pack, which directly affects seal performance and the service life of a brush seal. ...

Abstract: Structural parameters and inlet preswirl have great influences on the static and dynamic characteristics of honeycomb seals. In this paper, a multifrequency elliptical vortex dynamic model of a honeycomb seal was established ...

Abstract: The heat load caused by windage heating effect of labyrinth seals seriously influences the sealing of shaft air flow. To reveal the windage heating effect of labyrinth seals to reasonably design an aeroengine rotor, this ...
