Hello,

I am simulating the two-phase flow of water through a turbine nozzle out in the air.
I am using vof for the two-phase mixture and I have some trouble with the turbulence modeling.

The pipe that leads to the nozzle is 120mm long,the diameter
of the nozzle is 41.25mm and of the spear is 7.5mm.I am going to use three seperate turbulence
models and compare the results.The questions are about the appropriate boundary conditions.

I will use K-omega SST,k-e Rng with enhanced wall treatment and k-e realizable enhanced.
Can someone please tell me the appropriate BCs for each model?

For example when I use the default values for
Intensity=5 and visc ratio=10 I find significantly different results than using the defaults of k=1 and omega=1.

I hope I have made clear my question.

Thanks in advance
