Analysis of front plate's effect on low hysteresis brush seal

  • Aimed at different kinds of low hysteresis brush seals,computed them with porous medium model,and analyzed the pressure and velocity on upstream side of bristles,turbulence kinetic energy at the front and low part of bristles,discussed the effect of front plate on low hysteresis brush seals.The result indicates that front plate does not have obvious effect on upstream bristles' pressure,axial velocity and leakage of brush seals,but varies radial velocity on upstream bristles behind different kinds of front plate;the turbulence kinetic energy at the upstream and low part of bristles of the brush seal without front plant or with front plate too long is very big,the brush seal has front plate with holes got smaller turbulence kinetic energy at the upstream and low part of bristles than the other kinds of brush seal,and gets smaller bristle disturbance effect.
