Experimental investigation of lateral forces induced by flow through model labyrinth glands [PDF]
The lateral forces induced by flow through model labyrinth glands were investigated. Circumferential pressure distributions, lateral forces and stiffness coefficients data obtained are discussed. The force system is represented as a negative spring and a

Rotordynamic stability problems and solutions in high pressure turbocompressors [PDF]
The stability of a high pressure compressor is investigated with special regard to the self-exciting effects in oil seals and labyrinths. It is shown how to stabilize a rotor in spite of these effects and even increase its stability with increasing ...
