C_P(c,t) gives absolute or static pressure?

aditya.pandare · March 18, 2013, 02:47

Hi guys, I am new to the UDFs in Fluent and needed a little help.

I wish to know when we use C_P(c,t) in the UDF to get the pressure, do we get the static (gauge) pressure or the absolute pressure?

I read the fluent manual, and searched online too; but with no clear responses.
It will be great help if anyone would clarify this.

thank you in advance!

People on other threads think that its static pressure.
