Doubt in Inlet Pressure Boundary Condition
 
Hi friends,

I am doing my analysis in blower in that i have to give pressure inlet as 2000pa(Which is below Atmospheric pressure), my doubt is, in operating condition panel its default set as 101325 pa. So could pls some body tell me what value i should give in Operating Pressure and in Pressure Inlet Boundary Condition for my analysis. Thanks for ur time.

Hi,

Is this the case of Copmressible Flow ?

No its incompressible flow only devesh...

ok, Now as I know, fluent works on Absolute Pressure. So that if 2000 Pa is Gauge pressure then leave it as a default value of Operating pressure 101325 Pa.

you just put 2000 Pa in Total Gauge pressure at Inlet condition, rest keep it as defalut value. I think that may be helpful.
