Non-Contacting Finger Seal Developments and Design ConsiderationsA three dimensional Navier-Stokes based code (CFD-ACE+/FEMSTRESS) was utilized to analyze the thermofluid behavior of a modified FS. The pressure patterns, mass flows and load carrying capabilities of this structure were assessed. It was found that even at a lower linear velocity of 216mps (708 fps) the geometry proposed has good lifting capability.
