Hi guys,

i'm new to CFD and OpenFoam. I'm trying to build a simulation of a testfacility with 3 inlets and 2 outlets. It's build with wedges!

Now i have the problem, that I have no idea how to set the conditions for k, R and epsilon. I've read about a tutorial to calculate those values, but I can't find it.

Where can I found information about calculating them or is it possible to set empirical values?

Thanks beforehand and sorry for my bad english!

Hi Sebastian,

What solver are you planning to use?

Hi Gijsbert,

first step I want to use rhoTurbFoam. At first with k-epsilon. After that Spallart (is this possible with a compressible solver?) and with LaunderGibsonRSTM. At last I will try to solve the problem with coodles. The intention is to compare the different kinds of turbulence modelling and the les-solver!

But at first I want to get an running kepsilon-case!

Lot of information for such a short question! Thanks for your interest!
