Abstract
Annular gas seals are important components of rotating machinery. In the industry, some machines have presented instability problems due to the pressure and velocity distribution in the rotor-seal clearance. Thus, it is important to characterize the behavior in order to guarantee safety operation conditions. Aiming at this goal, a test rig is being built at the Federal University of Rio de Janeiro, int the Acoustics and Vibration Laboratory. This paper shows some preliminary experimental results.
