DOI: 10.1115/1.4040709
Abstract: Taking the flow field features of labyrinth seal into consideration, the fluid force generated from the seal cavity, which is spatially separated into two regions, is modeled with the perturbation method. The rotor orbit defined… read more here.

DOI: 10.1177/1687814017728455
Abstract: The pressure loads acting on the teeth of a labyrinth seal could differ significantly. Sometimes, one of the teeth would take almost half of the total pressure difference. This article makes an analysis of the… read more here.

DOI: 10.1177/1687814018794348
Abstract: The pressure loads acting on the teeth of a labyrinth seal are usually not uniform. Sometimes, one tooth would take almost half of the total pressure difference, which is detrimental to the teeth’s working life… read more here.

DOI: 10.3390/en14030705
Abstract: A straight-through labyrinth seal is one of the most popular non-contacting annular seals through which energy dissipation by turbulence viscosity interaction is achieved with a series of teeth and cavities. The geometric parameters of the… read more here.
