Determination of mixing quality/ uniformity index
Dear guys,
for a long time I had problems determining the mixing quality of a mixing line. Now I've come across a usable formula. I would like to share this with you.
It is the degree of uniformity also called uniformity index.
The calculation is cell-based.
U = 1 - (SUM^{N}_{i=1}(Ci-Cm))/(2*N*Cm)
with N cells
and concentration of a cell Ci
and the arythmetic agent Cm
Cm = (SUM^{N}_{i=1}(Ci))/N
The easiest way is to export the cells with concentration of the considered region (outlet) and create an Excel file.
Greetings Philipp

Hi, in your file I see two principal parameters, alpha and Area; for the Area ... What is the way you could get the data?
I would appreciate the answer.Posted January 24, 2021 at 20:24 by and2300

Hey,
so for the area you can use the spread-sheet in paraView. As I remember I think this is only possible in newer Version. I think I used OF V7.
Hope this helps!Posted January 28, 2021 at 05:38 by pconen
