This actually did the job. Thanks flotus1 !!!
Seems the problem is if I define inlet as "velocity-inlet", the velocity profile at inlet isn't that of a developed flow, and Poiseuille's law only...

@Far:
the fluid is water - viscosity 0.001003 kg/m-s = copied from fluent itself.

So I've run the simulation again today (with correct dimensions!!)
- Re is about 960 so it is laminar

Oh dear the dimensions were wrong, they were supposed to be mm, not cm, sorry!
Right I'll run the simulations again tomorrow with correct dimensions!

Just to clear things out: Only the one I ran...

So today I gave the simulation another try and I'm still not getting anywhere near the theoretical values.

Here's my case if anyone wanna try and see if they can get the desired results:
- Pipe...

Hello Jabba,

Yes it is incompressible flow. I guess my mesh should be at a reasonable resolution, because I set it as close to the limit as possible (the version I'm using is academic version so...

Thanks. I'll try this tomorrow and see how it goes.


Isn't this only used when the outlet pressure is a known value? That isn't my case, actually; I'm just trying to find the pressure drop...

Pipe flow simulation

Hello guys!

I'm a final year student trying to complete a project using Ansys FLUENT. One step of which is to try to simulate a 3D pipe flow, then compare the simulation results to Poiseuille's...
