Abstract

The recent years have seen an ever increasing amount of work in the field of brush seals. Fundamental and prototypal industrial research have attested to the improved fluidic and dynamic performance of such seals when compared to other classes of seals. This paper presents a continuation of the basic research performed by Braun et al. and further explores the nature of the flow and pressure patterns in configurations of dense array of cylinders simulating brush seal behavior. The investigation follows through the method of Full Field Flow Tracking (FFFT). The images supplied by the FFFT system are processed by means of a computer-integrated image quantification method (CIIQ) into quantitative information for flow trajectories and velocities. The tracking method permits identification and tracking of the same particle in a lagrangian frame of reference.
