Hi, I am trying to run a AMI Simulation. I like to run this with k-Omega-SST. But I still don’t know how to calculate k and Omega. I tried to understand many literature but it is still not clear. Maybe somebody can explaint this in a easy way? Thanks. :slight_smile:

Hy @vivien you can fine a detailed documentation about turbulence modeling here

@ Anware: I already studied this page, but I don’t know how I can calculate the turbulence intensity with the formula on the page? I don’t have u’.

ok @vivien here is the formulas Turbulent Kinetic Energy (TKE), k [Capture] Evaluation of turbulent dissipation [Capture1] for more info @1318980 will get back to you

Hi @vivien . Very much depends upon your setup. For an impeller you are probably drawing fluid in through a pipe, in this case you could calculate turbulent Intensity from the formula highlighted in this article: Defining Turbulent Boundary Conditions equation 4. Cheers, Darren
