The Effects of Vortex Generator Jet Frequency, Duty Cycle, and Phase on Separation Bubble Dynamics
… numbers. Experimental data collected using phase-locked particle image velocimetry and substantiated with a hot-film anemometer were used to answer fundamental questions about the influence of VGJs on a separated boundary layer. The data were collected on the suction surface of the Pack B …

Effect of diameter ratios on the flow-sound interaction of the straight circular finned cylinders
… _ Df =Dr _ 2.5 are considered. Results from the PIV measurements at Re = 20000 demonstrated that the extent of the recirculation region decreases downstream of the finned cylinders when the diameter ratio increases due to higher flow entrainment between the fins. The frequency spectra of the …

Phase Locked Flow Measurements of Steady and Unsteady Vortex Generator Jets in a Separating Boundary Layer
… LPT design. Data were collected using a stereo PIV system that enabled all three components of velocity to be measured. Steady VGJs were injected into a laminar boundary layer on a flat plate (non-separating boundary layer) in order to more fully understand the characteristics and behavior of …
