An Approximated Method of Calculating the Cellular Insert Influence in the Carrying Capacity of the Direct-Flow Labyrinth Seal

摘要

A method for calculating the flowrate of the gas flowing through the cellular insert cells over the labyrinth seal strip is proposed. The gas density is taken to be average with respect to the decisive section. It is assumed that jets flowing out of cells disrupt the direct flow of the labyrinth seal. A practical implementation of the method is confirmed by the known experimental data.
