Hi all, I am trying to calculate pressure drop for the attached image of a cell cooling plate. The only problem is I could not understand how to calculate average absolute pressure at inlet and outlet for this model. I am open to your ideas, please share.

I am using fluent for analysis, the flow is laminar, and the K-Omega solver is used for the calculation.

Hello, 

 

Fluent always uses the gauge pressure. However, if you set the Operating Pressure to zero, your gauge pressure becomes the same as the absolute pressure, which can be determined using reports. Caution needs to be taken while setting operating pressure to zero. Check this for more information: ANSYS FLUENT 12.0 User's Guide - 8.14.3 Setting the Operating Pressure (enea.it)

 

Thanks,

Nikhil

In fact, if you have set the operating pressure the same as the atmospheric pressure, you can simply determine both the static and absolute pressure, directly from the reports.

Thank you very much Nikhil. I will do the same.
