PIV

PIV = Particle Image Velocimetry, means illuminating small particals (tracers) in a fluid and calculate velocity-vectors using displacement of those tracers between two pictures. Shown here is a video of tracer-movements caused by convection currents. Illumination by a 2 watt argon-ion-laser.

Hi, I am trying to do a similar experiment. Do you recall the fluid medium, seeding particles, and/or the frame rate of the camera used? Thanks! I would really appreciate the help.

hi, the fluid is just water (Bénard cells). the particles are hollow glass spheres (110P8, Potters Industries) with an average diameter of 10 µm. I'm sorry, we didn't document the frame rate, since this video was just for fun... have fun!

Hello, i´m from Mexico City, i´m going to present my thesis about PIV tecnic, can i put this video on it? please answer

thanks- that helps!
