wall functions value
 
Hello everybody!

Im pretty unexperienced in OpenFoam / in this forum .

I have some trouble understanding the function of the value at the wall funktions. There is a value at espilonwallfunction and omegawallfunktion. I changed the value at the epsilonwall funktion by multiplying it by 100. That didn't seem to change anything. in the actual modell the value is 1.6.. I took it from another modell.

So my question is what is this value?
what is its meaning /
what is its influence on the modell?
how can I calculate the value for other modells?

Thank you!!
