| Summary: | and radial components of velocity near the bristle surface. are correlated to obtain an estimation of the flow through associated bristle configurations. Comparisons are made because the large stagnation pressure force predominately in between seals of different bristle angle, bristle diameter, bristle free length, seal backplate diameter, and lift-off bristle tip region. Experimental and numerical leakage data configurations can greatly influence the leakage. The moment developed to compute the three-dimensional details in the dimensional flow field, showing the circumferential, axial, due to the forces acting at the bristle tip can increase the examining the flow through different seal geometries and For all seals considered, the radial force component is gap. Numerical flow visualization illustrates the three- gap. The result of the investigation reveals that the geometry of the brush seal and associated bristle lift-off gap which may increase leakage through the seal. Major flow characteristics (separation and recirculation) observed in the circumferential direction. occur within the inter-bristle spacing and in the lift-off significantly greater than the tangential force component The complicated fluid flow at the tip of a typical bristle the overall brush seal. A parametric study is conducted by the radial direction prevails over the smaller shearing force within a brush seal is simulated. A numerical model is |
