homogeneity index lambda / Es-ice
Hi Everyone,

Does anyone of you use a homogeneity index to analyse the lamda distribution within the cylinder? I am looking for a formula to define this index. Can anyone help me?

Many Thanks in advance,

Re: homogeneity index lambda / Es-ice
I've never used a homogeneity index for that kind of simulation, but I think the simple thing you can do is to compute the standard deviation (or variance) of the lambda itself, inside your can consider the lambda in every computational cell and its deviation from 1 as a dis-homogeneity index
