| Summary: | a honeycomb seal. The leakage comparison demonstrates that across the seal, the honeycomb seals have better rotordynamic against rotation. For high speed and high pressure ratio and (b) using shunt injection. In some cases, labyrinth Centrifugal compressors are increasingly required to operate control due to the higher density of the fluid. damping decreases for the labyrinth seal with injection discharge volute, and injected into an upstream cavity of the have successfully been used since 1970s, this thesis contains in higher pressure, higher speed, and large fluid density. In these conditions, compressors are susceptible to injection against rotation will have a better performance due labyrinth seal. The injection can be radial or against labyrinth seals have been modified by (a) using swirl brakes, labyrinth seals with shunt injection the worst. For low and labyrinth seals, with and without swirl brakes, labyrinth medium running speed, and most conditions, the labyrinth seal other hand, honeycomb seals will have a better stability performance. In centrifugal compressors, the selection of rotation. Even though labyrinth seals with shunt injection rotordynamic instabilities. To avoid this situation, seal with shunt injection (radial and against rotation), and seals have been replaced entirely by honeycomb seals. In shunt injection, and the labyrinth seal with and without shunt injection, the gas is taken from the diff-user or shunt injection. A comparison has been made between stability followed in order by the honeycomb seal, radial swirl brakes. When running speed increases, the effective the first measured rotordynamic data for labyrinth seals with the honeycomb seal has the best flow control, and the the seal should be cautiously analyzed. Seals with shunt to possibility of a higher pressure injection ratio. On the with injection against rotation has the best rotordynamic |
