The Particle Shadow Velocimetry (PSV) technique is utilized for velocity measurements near walls, in cavities, and near model surfaces. Measurements are made on a readward facing step, a cylinder in cross flow and in an open water cavity. Velocity information obtained by two different analysis approaches, traditional grid based and particle centric cross-correlations, are compared. It is shown that the particle centric methods yields more details in complex flows. This paper shows that the PSV technique is well suited for measurements near surfaces where conventional laser-based PIV methods are hampered by surface glare and/or optical access.
