cyclone separator pressure measurement vs cfd
1 Attachment(s)
hi all,
i am currently simulating a cyclone separator, i want to check the pressure drop and compare with experimental data. i am not quite sure which value is reported at a certain position in scientific paper, i think only a point measurement for pressure is made (?), if so, should i also use a random point at the wall in my cfd simulation or take the average from a cutting plane? a screenshot is attached. thank you for your time. |
If you just take a point, you can move it around until you get the same value as you find in the experiment ;-)
Usually I would use a mass-flow-averaged pressure across the surface. |
I know the area avrg pressure = 1/A * Sum ( p_i * A_i)
What does the mass-avrg pressure look like ? |
Replace the A_i with the mass-flux for the face and A with the whole mass flux across the section.
