Development of a low cost 3D Particle Image Velocimetry for sub-sonic wind tunnel applications in Idaho State University.

PIV is a non-intrusive technique that provides instantaneous velocity vector measurements in a cross section of a flow. The stereo or 3D PIV technique is a topic of current interest due to its capability of 3D mapping of the vector field. We present in this paper an approach to build a low cost 3D PIV system for sub sonic wind tunnel applications as well as the related basic CFD studies.
