CALCULATION OF LABYRINTH SEALS WITH EXTRACTION

摘要

The paper presents a method for ealculation of labyrinth seals with extraction. It involves a disorder of movement by interfering with the flow and bringing some irrelevant value of the mass stream out of a specific point of the labyrinth packing and outside the seal. It is described how to detect changes in the seal geometry by introducing a diagnostic parameter. The results of calculations arc determined by an algorithm based on linearizations of de Saint - Venant equations.
