The anisotropic porous model covering the bristles bending deflections was used to establish the calculation model.The effect of bristles for the flow media was considered a resistance force

which was added into N-Sequation as a source term.The model was established on the basis of the Finite Volume Method and the SIMPLEmethod.To this effect

the pressure field

velocity vectors distribution and leakage of brush seal were obtained from calculation of flow field.The influences of main parameters

such as: structure and working condition

on the sealing performance of brush seals

were analyzed and compared

showing that this method is suitable for the study of the brush seals.
