pressure drop

I want to model pressure drop in ducts. It should account for friction and shock losses. It is hot gas flowing (max speed around 20-25 m/s) through large ducts. Does anybody have experience solving this kind of problems with OpenFoam or any other package? Solving Navier-Stokes would be enough or I need to solve energy (and maybe k-e model since the flow is turbulent) as well?

How does surface roughness comes into the picture?

Any help is greatly appreciated...
