27 de mar. de 2023 · This study has focused on the erosion effects in different labyrinth seals of the Francis turbine. Labyrinth seals are non-contact seals used for minimizing unwanted leaks between stationary and rotating parts. The labyrinth consists of two parts: a static seal connected to the turbine covers and a rotating part connected to the runner. The ...

1 de ene. de 2003 · This paper focuses on the flow within the inlet cavity of a turbine rotor tip labyrinth seal of a 2 stage axial research turbine. Highly resolved, steady and unsteady 3-dimensional flow data are ...
19 de feb. de 2015 · A method of seal leakage calculation was developed. It connects engine thermogasdynamics calculation, airflow hydraulics calculation and structural analysis of deformed parts. The main sources of heat transferred to the supporting element were determined; their numerical values and percentages for the compressor and turbine were also determined.
1 de may. de 2016 · 1. Introduction. Rotordynamic characterization of seal was initiated five decades ago by Alford [1]; and since then drawing enough attention owing to the repeated occurrence of stability related concerns associated with the gas turbine engine.Towards addressing this issue, new seal designs like fully partitioned damper seal [2], hybrid brush seal [3], radial-annular seal [4] and hole-pattern ...
