when examining a tube axial fan model, surface goal of
velocity pressure at outlet in the direction of flow was very high
at outlet ,this may be refers to high swirl produced from the fan
blades that makes air come and go across this surface ....I 'm not
sure .A straightener was modeled to simulate real life to make it
stop this swirl and flow through this part was simulated and it's
pressure drop was found.it will be assembled inline with the fan .
what is the best way to cancel the drop of the straightener ?
1-to add an inline fan at outlet boundary condition? if so how can
I insert Goals at outlet
2- to initially put static pressure below atmospheric pressure at
outlet boundary condition to cancel the pressure drop it a fan
element need to be put inline with
