Hi!

As I have just started using Open Foam I would need some help to set a case

I want to compare a calculation of a nozzle flow, made with Fluent to one with Open Foam and need to install similar boundary conditions in Open Foam as used in Fluent.

At the inlets, in Fluent I have installed pressure-inlets to set up the total pressure. Furthermore, at the outlets, there are defined pressure-outlets with a given static pressure.
Now I want to do the same in my OpenFoam case. Which BC would you recommend (also in respect of possible backflow)? Also, which BC should be used for k and epsilon? In Fluent I set the trubulence intensity and the viscosity ratio as fixed values. I think the turbulentIntensityKineticEnergyInlet for k is the corresponding BC in OpenFoam. But what to use for epsilon?

Thanks in advance!

Sebastian
