Applications of PIV techniques in various engineering researches of flow measurements were summarized in this section. As mentioned before, technique of measurement of PIV was developed to measure turbulent flows of wall bounded [4, 5]. One of the advantages of PIV is whole flow field can be measured with minimal disruption in instrumentation. The main difference between PIV and other techniques measure velocity just at a point. Meanwhile, PIV can provide two-dimensional or three-dimensional vector fields [6]. Particle concentration is possible to identify single particles in an image during PIV is operated [6]. There are many studies on fluid measurements that require PIV technique to capture the flow velocity and vortex of stupendous flow fields outrightly
