    Abstract
  • An analysis model of a herringbone-grooved finger gas seal system was presented for its structure and working parameter.The dynamic leakage and dynamic load capacity were subsequently calculated.With this model,analysis and calculation were performed with the change of different herringbone-grooved parameters and working conditions for the sealing performance of the seal.The calculated results indicate that the sealing performance is straightly affected by herringbone-grooved parameters.Rotor speed and windage have different influences on the leakage and load capacity.The above results are validated by comparing with the test data in references,thus providing a better basis for design of the seal.
