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.
An example is shown in my public dropbox:
Greetings Philipp
