Bragg, Michael B. Gurbacki, Holly Marie 2015-09-25T22:34:20Z 2015-09-25T22:34:20Z 10000-01-01 2003 2003 Vortex structures observed in the shear layer were presumed to be the cause of large-scale pressure fluctuations upstream of reattachment at small angles of attack. Pressure spectra near reattachment exhibited wide bandwidth frequency peaks that indicated a non-periodic phenomenon and corresponded to the regular mode often associated with vortex movement in and aft of the shear layer. Strouhal numbers ranged from 0.53 to 0.73. Although vortex shedding was rarely observed, the convection of surface pressure fluctuations occurred at approximately half the freestream velocity, similar to shedding velocities reported by others.
