Hi,
I have a long pipe with 2 pressure gauge in it, static pressure gauge/
When I measured pressure in real (examination test in my laboratory) I got pressure of 1.46 bar and 1.27 bar
When I tried to simulated that in flow simulation my input boundary condition was of 1.46 bar static pressure as inlet pressure but as you can see in the
picture the pressure in the other gauge is 1.41 bar not 1.27 bar as in real test i did
What could be the problem?
Thanks,
Oshri
Thanks mark
Is there a option to add roughness only on the pipe part? and how?
Oshri,
Insert / Boundary Condition / Pick the surface / Type = Wall / Rz = roughness in micro meters.
Us
e Flow Sim Help to look up 'Boundary Condition' Cheers, Mark
Thanks mark
asking again
is it possible to insert the roughness only for the pipe (part) not for all the assmbley?
oshri
the method that mark describes is face by face
if you want to apply to all, the easiest is to set the default in the study options
regarding your initial problem, you'll have to describe your problem a bit more. you said you have a pressure inlet, what is your other boundary condition?
what is the goal of your analysis?
Possibly you need to add surface roughness to the pipe and this would reduce the pressure.
Check to see that your gages are calibrated. Look at both your test setup and the simulation setup for refinement. Cheers, Mark
