compressible flow, rhoSimpleFoam, boundary conditions

I'm trying to solve a compressible flow with rhoSimpleFoam but I can't get it to converge. I believe it is a boundary conditions issue as simpleFoam does run ok on the same mesh (for lower velocity, incompressible cases).
The topology consists of one inflow and two outflows (please see the attached image to get the idea). My problem is that I cannot find the right set of boundary conditions for the patch in coloured in red on the image.
All variables are known at the inlet.
I'm not sure if this makes any difference but that's the thermophysical properties I use:
Can someone suggest what set of boundary conditions could work with rhoSimpleFoam?
Thanks a lot!
I use OF 3.0.1 but I could also use OF 2.3.1.
