Advances in Brush Seal Numerical Modeling

This paper presents a general review of the experimental, analytical/numerical and industrial state of the art in the development of brush seals. The authors further present their numerical model as it relates to the physics of the flow, as understood from the numerous experiments done in the hydraulic tunnel at The University of Akron. Based on their own experimental and numerical work the authors propose a new approach to the solution of full brushes. This approach involves the segmentation of the brush in repetitive core segments, bound by an inlet and an exit segment. A numerical experiment is performed to prove the validity of this concept.
