EXPERIMENTAL ROTORDYNAMIC COEFFICIENT RESULTS FOR TEETH-ON-ROTOR AND TEETH-ON-STATOR LABYRINTH GAS SEALS uri icon

abstract

  • An experimental test facility was used to measure the rotordynamic coeffcients of teeth on rotor and teeth on stator labyrinth gas seals. Direct damping coefficients are presented for these seals. The results are presented for the two seal configurations at identical operating conditions, and show that, in a rotordynamic sense, the teeth on stator seal is more stable than the teeth on rotor seal, for inlet tangential velocity in the direction of rotation.
