A Beginner's Introduction to Particle Image Velocimetry (PIV) using MATLAB - Part 1

In this video, I start a formal theoretical discussion on the basic idea of particle image velocimetry (PIV). Please use the following links to explore a bit further:

you made this so simple.. loved it.. thank you so much.

Thanks a lot for ur effort, this video is really helpful. I am using piv, How can I measure or calculate the particle size plz ?

If u can answer my simple question that would be very beneficial
1. What is the size of image in mb which Is getting generated
2. Why we are not taking a video
3. Why we need synchronisation if we can just continuosly keep on the laser and just click images...no need to synchronise the camera and laser on off..?

I like your video so much! thanks a lot

It is an excellent video bro. Will you be showing anything about plotting contour of mean velocity and mean Vorticity using Matlab after post proccessing? I know the questions are silly, but I'm a beginner in Matlab.

Hello Tanmay, thanks a lot for your explanation. Since the laser sheet is very thin, what if particles move around and couldn't be illuminated by a laser beam? Won't this affect experiment results? Thank you!

Why do you use a laser with a wavelength between 400-500nm?

Hey, thanks for the nice PIV videos in your channel! Thats very much appreciated! We're planning to measure flow velocities of sediments in a settling chamber. As these particle have different sizes i want to calc velocities for different size ranges. Did you do calculate particle size distribution and categorized velocity estimations with piv already and could you provide information on that or even make a video? :) thanks again!

I am using piv in thermoacoustuc device oscillatory flow.The flow medium is air and smoke from insence sticks. Do u recommend me to keep using this type of smoke ??
Many thanks

Hi thank you for your awesome video, May I use the blueprint of the PIV(the picture with numbers 1, 2, 3, 4) for my school presentation? For reference, I go to high school.

Hey, good afternoon. Do you think I can survey the velocity of the tide in situ in a lagoon by using the particles which are already flowing in the water (sand, phytoplankton etc). All the best, Ben

Hello Tammy ..we are planning to build a PIV for our final year project..do youhave your paper regarding this or is there any way to contact you on Facebook/WhatsApp/phone
