PIVlab - Time-Resolved Digital Particle Image Velocimetry Tool for MATLAB
收藏资源简介：
PIVlab is a time-resolved particle image velocimetry (PIV) software that does not only calculate the velocity distribution within particle image pairs, but can also be used to derive, display and export multiple parameters of the flow pattern. A user-friendly graphical user interface (GUI) makes PIV analyses and data post-processing fast and efficient.<br><br>Video about the tool:<br>https://www.youtube.com/watch?v=Sp3Ounq07Qc<br>Example analyses & videos can be found on the PIVlab website:<br>http://PIVlab.blogspot.com <strong>Please ask your questions in the PIVlab forum: </strong><br><strong>http://pivlab.blogspot.de/p/forum.html</strong> Peer reviewed paper on PIVlab: <strong>Thielicke, W and Stamhuis, E.J. 2014</strong>.
