A numerical code has been developed to determine the rotordynamic coefficients of straight-through labyrinth gas seals in the case of a single volume model.Some considerations are drawn concerning the position of the sonic section when the flow is choked.

Rotordynamic Coefficients for Labyrinth Gas Seals: Single Control Volume Model
2002
Abstract
A numerical code has been developed to determine the rotordynamic coefficients of straight-through labyrinth gas seals in the case of a single volume model.Some considerations are drawn concerning the position of the sonic section when the flow is choked. Furthermore the influence of kinematic viscosity varying with pressure has been considered. The results are compared with the experimental and theoretical ones available in the literature. The agreement between results is fairly good.File in questo prodotto:
