Particle Image Velocimetry (PIV) allows global velocity measurements to be obtained in a flow simultaneously at all points in a plane. This is extremely useful for studying, for example, the behaviour of vortices in a flow. Rapid advances in computing and digital imaging have facilitated the development of the PIV measurement technique. To perform PIV, a flow is seeded with tiny particles (like smoke) and illuminated using a powerful laser. Successive images of the flow are captured using a high speed camera and compared using particle tracking algorithms. The end result is a full array of velocity vectors throughout the flow field. Since UNB already has a laser and high speed camera suitable for PIV (the most expensive parts of a PIV system), we are requesting the final hardware and software pieces to build a fully functional PIV system. The understanding gained from this tool will allow for the development of quieter and more efficient vehicles and will be used to improve the efficiency of industrial processes.
