v27 v28 2 2 = [wiki:Tutorial] / Advanced Particle Imaging Velocimetry = 3 3 4 This is an example using more advanced tools than the simple example [wiki: "Tutorial: Particle Image Velocimetry"Tutorial: Particle Image Velocimetry].4 This is an example using more advanced tools than the simple example [wiki:Tutorial/ParticleImageVelocimetry Tutorial: Particle Image Velocimetry]. 5 5 Image pre_processing and merging of mutiple fields is used to optimise PIV in the case of a narrow parietal jet (produced by convection in a cavity). 6 6 Open the example UVMAT_DEMO6_PIVconvection (accessible on http://servforge.legi.grenoble-inp.fr/pub/soft-uvmat/). … … 18 18 19 19 = First PIV = 20 Do PIV on the the whole image series, selecting all the options from Civ1 to Patch2 (see [wiki: "Tutorial: Particle Image Velocimetry"Tutorial: Particle Image Velocimetry] for an introduction).20 Do PIV on the the whole image series, selecting all the options from Civ1 to Patch2 (see [wiki:Tutorial/ParticleImageVelocimetry Tutorial: Particle Image Velocimetry] for an introduction). 21 21 22 22 Choose the pair 'j=1-2' which provides the smaller time interval (100 ms), a good choice to capture correlations in a first try (although higher precision can be obtained with a larger time interval if the correlation is still of good quality).
