Hi all,

I had a question about doing an OpenFOAM simulation where I model a diffuser test section on a rectangular domain. The pressure gradient due to the diffuser opening angle would be added as a forcing term to the NS equation. Is it possible to something like this in OF? What sort of boundary condition would I be looking at for the diffuser walls?

The physical geometry would be a rectangular section followed the diffuser opening. So the computational grid would have a pressure gradient that ramps up from 0 to a pressure gradient value.

Any tips or suggestions are welcome.

Cheers
