Default 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,

Franck

Hi
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 chamber...you can consider the lambda in every computational cell and its deviation from 1 as a dis-homogeneity index
