How apply pressure gradient to get fully developed flow?

Hi, I'm working on a problem that deals with cylindrical obstacles being used as turbulence promoters in a laminar flow in a pipe. I need to achieve a fully developed flow at the pipe inlet and the base paper I'm working on says that they achieved this by "imposing a constant mean pressure gradient until the flow reached a statistically stable state".
So does anyone knows how to do this? I mean what kind of BC do I employ? I don't want to change the pipe length for every different Reynold's number simulation and change the geometry in GAMBIT and do the simulation all over again.
Please help me out guys
This is the excerpt from the paper where the "problem formulation" is given:
