    Abstract
  • The flow field of a two-stage low hysteresis brush seal with certain structure was computed with porous medium model. The relationship between seal installation angles, front and back plate gap clearance height of the second stage and partial pressure ratio were also analyzed. Based on cantilever beam theory and the pressure distribution, bristle forces and deflections were calculated with the finite element method, and the effects of parameters on friction torque and inter-stage imbalance were discussed. The result indicates that, increase of the first stage bristle angle and decrease of the second stage bristle angle could make the partial pressure tend to equilibrium. With the given structure of first stage seal, different front plate gap clearance heights of the second stage seal have little effect on inter-stage imbalance, and a specific back plate gap clearance height can make the two stages get an equilibrium state.
