1 de ene. de 2002 · This paper examines the impact of labyrinth seal leakage flow over the rotor shroud on the loss generation in an axial turbine stage. Numerical studies have been carried out with an in-house ...
FUNCTION AND SYSTEM LAYOUT The two functions of the turbine glands and seals are:1 To prevent or reduce steam leakage between the rotating and stationary components of the turbines if the steam pressure is ... gland can withstand higher steam conditions than the carbon ring gland. Figure 9.1 ( a) illustrates a simple form of a labyrinth seal.
1 de nov. de 2023 · The labyrinth consists of two parts: a static seal connected to the turbine covers and a rotating part connected to the runner. The labyrinth gap is small for a new turbine and so the leakage is low.

30 de nov. de 2023 · Abstract. This paper presents a study conducted on a new gas turbine designed to limit leakage in the labyrinth seal. The slots in the fin are used to generate a bypass flow, which obstructs the flow in the gap above the fin. The method was tested numerically and experimentally beforehand using a simplified model without rotation or blade passages. In this paper, the validation of the method ...
