GPIV: GNU software for Particle Image Velocimetry (PIV).

Large part of my research on fluid mechanics deal with experimental techniques. Fortunately for all of us , Dr. Gerber Van der Graaf created a project that allows us freely analyze experimental images by means of PIV. I suggest that interested people should strongly support the GPIV project, adding new features, reporting bugs, or only recommending its use to their collegues world-wide. I tested it, and the results were just excellent. Currently I am using GPIV for data analysis with high success. More information:

Synthetic Image generator for Image Velocimetry

As you probably know my work is related with Particle Tracking Velocimetry(PTV). Currently I'm developing new 2D and 3D algorithm. Normally, I was using the synthetics images of the Visualization Society of Japan, but I needed some special characteristics in the image that were no available. To solve this I create a Synthetic image generator for Matlab. To use it, is necessary to introduce a velocity distribution, for instance the results of Large Eddy Simulation (LES). The equations were taken from the book: "Particle Image Velocimetry" written by Mr. Raffel. If some one need the source code, please do not hesitate to contact me.

Chilean Conference on Hydraulics

This year the XVII Chilean Conference on Hydraulics (5- 7th of October) will take place in Valparaiso (6th región) and will be organized by the University Federico Santa María. The invited speakers (at the moment) are Prof. John Gulliver from the University of Minnesota and Senator Antonio Horvath.
