CHAMBERS OF LABYRINTH SEALS OF TURBINE ENGINE
Original language description
This article explains flows in labyrinth seals of turbine engine. The aim of this article is to describe the flow in the labyrinth seals as a function of radial clearance and the number of sealing tooths at a constant pressure drop and rotor speed. Firstly, this aim is achieved by 3D CFD flow simulation based on seal demonstration for which dimensional and thermodynamic parameters corresponds with turbine engine. The simple profile of tooth of labyrinth seal, which simulated the conditions, was based on real machine setting. The result will be the description of the flows in the chambers of labyrinth seals at various radial clearance and different number of seals. Flows description can be done by using a flow coefficient. Mentioned variable will clearly demonstrate on previously stated parameters the impact on machine´s functionality.
