Seedless Velocimetry Measurements by Schlieren Image Velocimetry
AIAA Journal, 2011Schlieren optical systems have been used to perform velocity measurements in refractive turbulent flows using particle image velocimetry algorithms. This schlieren image velocimetry (schlieren "particle image velocimetry") technique makes use of naturally occurring refractive turbulent eddies in a flow as virtual "seed particles" upon which velocimetry
