Designing a flat-walled diffuser
 

Greetings all,

I'm a beginner and currently learning the basics of CFD theory alongwith applying the day-to-day learning in Fluent/Gambit.
I seem to have hit a snag with diffusers. More specifically, I'm looking to design a flat-walled diffuser with given outflow rate & outlet pressure.
I'd be grateful if anyone with experience would help in chalking out the fundamentals I need to keep in mind in this design process.

Thank you.
:)
