I would like to know how to measure the Mixing index of two different types of fluids if I analyzing the whole set up under the Micro-Particle Image Velocimetry system (Micro-PIV).
1 Is it possible to analyze the image captured by the CCD camera attached to the Micro PIV system and then process the image by using the MATLAB program?
2. Is there any other possible way?
Hi Mohammad, you can make image processing by using the PIVlab tool: https://www.mathworks.com/matlabcentral/fileexchange/27659-pivlab-particle-image-velocimetry-piv-tool. You must have the image processing toolbox in Matlab to use it. There is also a tutorial in Youtube about PIVlab which is very helpful. Also, for PIV image processing you can use the OpenPIV, it is written in Python. You can find it here: http://www.openpiv.net/openpiv-python/.
As for the mixing index, do you have the ability to use Laser Induced Fluorescence Method? By using this method you can calculate the mixing index. The experimental setup in PIV and LIF is the same (Laser, CCD camera, microscope, power supply of the laser, timer box etc.) The most common tracer compound for LIF method is Rhodamine B.
Thank you very much
Yes we add Fluorescence as tracer particle then use synchronized laser emission system to capture the image
