Eddy Interaction Model(EIM)
 

Hi all.

i wanna write a code for simulating particle dispersion in grid turbulence experiment of Snyder & Lumly. I wanna use eddy interaction model.
in my code when eddy life time turn over, code generates a gaussian random number and multiplies to RMS. then adds this value with mean velocity and uses it for particle equation of motion.but when i compare particle dispersion to results of articles is not correct. can any one help me?

and i wanna know random number multiplied to RMS, must be identical in each direction or no?

EIM in CFX
 

Hi
I'm using k-eRNG model for wave plate mist eliminator problem,I want to know how can I apply the constant EIM model for turbulent dispersion in cfx 14.
tnx
