000013982 520__ $$2eng$$aIn annular pressure seals used in turbomachinery, the leakage of working fluid is reduced by the acceleration-deceleration effect of the fluid through a convoluted path. In order to better understand the mechanism that govems the leakage rate, this study proposes the utilization of Reduced Order Model and snapshot techniques. The goal is to study the energy distribution of the flow field by replacing a huge number of governing PDEs with only a few ODEs, to describe a complex system. As the results indicate, the first few modes contain the majority of the energy, therefore only these first few modes are needed to recreate the flow field. It is shown that energy distribution is concentrated on the clearance region. Considering that seal design studied is not efficiently using the space inside the grooves, a potential improvement from the energy flow point of view can be carried out to increase seal performance.
