Pressure drop in cyclone separators.

arjun3020 · February 23, 2012, 07:08

Hi all,

Could you please tell me how to find pressure drop in cyclone using CFD post or fluent?

i have pressure contour which gives highest pressure of 1005 Pa. and lowest pressure of -303 Pa.

How to find actual pressure drop in cyclone?

See the attachment of contour.

Hi Arjun,
Difference between "Area weighted average" of static pressure at Inlet and Outlet will give you your pressure drop

Luke

basically you have two planes in the domain i.e the inlet and the outlet

in fluent go to report data pressure absolute pressure and print the values of the pressure at the inlet and the outlet and take t he difference of the both

you are done
hope that help you
