Improvement of Labyrinth Seal Leakage Rates Using Additive Manufacturing
… using additive manufacturing to develop better labyrinth seals in turbomachinery. Labyrinth seals have a torturous fluid path with high losses, thus limiting the amount of fluid leakage. These types of seals can be non-rotating, allowing them to better take advantage of the additive …

Computational Fluid Dynamic and Rotordynamic Study on the Labyrinth Seal
The labyrinth seal is widely used in turbo machines to reduce leakage flow. The stability of the rotor is influenced by the labyrinth seal because of the driving forces generated in the seal. The working fluid usually has a circumferential velocity component before entering the seal; the ratio of …

Labyrinth Seal Preprocessor and Post-Processor Design and Parametric Study
… the non-uniform pressure distribution within the labyrinth cavity is identified as a major source of this excitation. In order to perform rotor dynamic evaluation of rotor-bearing-seal system, accurate prediction of this force is essential. A visual basic based front-end, for a labyrinth seal …

Study of Forces and Dynamic Coefficients in Whirling and Eccentric Labyrinth Seals Using ANSYS-CFX
Labyrinth seal force estimates are important to the prediction of the stability of turbomachinery. The force prediction methods fall into several categories: experiments, bulk flow analysis, and finite volume analysis. Finite volume analysis can be split into two subcategories: self-developed and …

Rotary fast tool servo component design
… angular sensor for position feedback, and a labyrinth seal system to protect the rotary axis hearings. The design of the tool arm meets several conflicting challenges, including maintaining low rotational inertia and high stiffness while providing an integrated tool height adjustment …

Large Eddy Simulation of Labyrinth Seals and Rib Shapes for Internal Cooling Passges
… source of loss in turbomachinery. Therefore labyrinth seals are also investigated in this study, attempting to reduce the flow leakage and further increase the turbine efficiency. Large Eddy Simulation ( LES ) is used for its capability to capture the complex unsteady flow features in this …
