| Summary: | Analysis has been done for LDV measurements of the flow through centered and statically eccentric annular seals. The effects of both positive and negative preswirl upon the mean velocity, Reynolds stress tensor, vorticity, turbulence induced accelerations, mean accelerations, and turbulent kinetic energy are presented. Among the main findings are a diffusion of axial momentum toward the rotor, a journal bearing type pressure field which causes migration of axial momentum around the rotor, and axial vorticities that vary with preswirl while azimuthal vorticities do not (which supports assumptions made in bulk flow theories). |
