(August 2012) Serafettin Ustun, B.E., Gazi University, Turkey; Chair of Advisory Committee: Dr. Gerald L. Morrison Annular seals are devices, which are used in turboMachinery systems to reduce the flow leakage, and to provide better dynamic stability to the system. Leakage flow can strongly affect cooling quality, heating balance, and efficiency of a turboMachinery system. Due to the fact that annular seals can significantly reduce the flow leakage, and provide the most cost-effective way of enhancing the aerodynamic efficiency, understanding of the flow characteristics through the annular seal configurations is an important subject. Seals are classified in two main groups, which are contacting, and non-contacting seals. Straight annular and convergent seal configurations are characterized as noncontacting seals, and they are widely used in rotating turbocMachinery systems. The flow kinetic energ...
