Knowing the precise time (Dt) between the double laser pulse provides a reference for the spacing and direction change between these particles in the image sequence. The tracer particles can then be tracked for movement in the flow where each image is analyzed for the position of these particles as a function of time. The short intense laser pulse provides an excellent contrast to the tracer particles after capture. When the laser illumination is off, the image is completely dark. The laser illumination is very short in duration, easily stopping all motion. These tracer particles will be very visible in the flow when pulsed with a sheet or spot laser illumination. To facilitate visualization of a flow, most applications require seeding the flow with tracer particles. Flows in Devices for Life Sciences and Biomedical Work.Flows in Pumping and Rotating Machinery.As an example, the high temporal rate allows visualization of the laminar separation bubble found in the flow over an airfoil, turbulent flow near an object or complex flows found in bioreactors. PIV is very useful for analysis of turbulent flow, transient flow, micro flow and 3D volumetric flow studies. The technique is used to obtain the time dependent velocity distributions in a Field-Of-View (FOV) of single and multi-phase flows which are very fast, turbulent and complex. This application note will give a brief overview of Particle Imaging Velocimetry (PIV) for flow visualization using PhotronРІР‚в„ўs high speed FASTCAM cameras.
