We studied the grid-generated turbulence by using Particle Image Velocimetry (PIV) technique. test on this already well flow new ways of analyzing spatially resolved PIV data, such as spatial spectra and structure functions. compare some characteristics with results Laser Doppler Anemometry (LDA).

Investigation of Relative Importance of Some Error Sources in Particle Image Velocimetry

This paper examines various techniques that have been developed to measure flow fields in microfluidic devices with 10 – 10 micron-scale spatial resolution. These techniques include Scalar Image Velocimetry (SIV), Laser Doppler Velocimetry (LDV), and Particle Image Velocimetry (PIV). Advantages and disadvantages of these techniques are presented. PIV results are presented for a liquid flow thro...

Flow dynamics in intracranial aneurysms and their adjacent parent vessels play important roles in the development and rupture of intracranial aneurysms. Combined with tagged MR imaging and the use of particle image velocimetry software, tagged MR image velocimetry reveals flow vectors, vorticity, and shear strains at each location in the aneurysm replica every 9 milliseconds. This technique is ...
