An evaluation of preliminary Doppler global velocimetry measurements [PDF]

open access: yes
A review of Doppler Global Velocimetry (DGV) data obtained during wind tunnel tests on a 75 degree swept delta wing was performed. High frequency variations observed in normalized data files are attributed to image alignment problems.

Flow and Cavity Measurements in a Super-Cavitating Propeller

open access: yesJournal of Marine Science and Engineering
The design of super-cavitating propellers takes advantage of the development of air cavities on the blades’ surface to reduce drag and, ultimately, increase efficiency.

Experimental measurements of the laminar separation bubble on an Eppler 387 airfoil at low Reynolds numbers [PDF]

open access: yes
An experimental investigation was conducted to measure the flow velocity in the boundary layer of an Eppler 387 airfoil. In particular, the laminar separation bubble that this airfoil exhibits at low Reynolds numbers was the focus. Single component laser

Preliminary study of a wing-tip vortex using laser velocimetry [PDF]

open access: yes
Measurements have been made in the wake of a semi-span NACA 0015 airfoil with emphasis on the region of the wing tip vortex. The spanwise and streamwise velocity components were measured using a two-component laser Doppler velocimeter. The purpose of the
