Is generating RGP worth it ?

Syed Wajeeh · February 7, 2025, 07:28

Hi there experts !!
I am trying to find the pressure drop of gaseous oxygen in a coiled pipe. The issue is that actually during the flow, temperature of GOX will vary from 150-400K which will alter it's density. Also as we know that density also depends on the pressure. So I want to know that, for close to real life scenario for this flow, should I go for RGP tables (which seem to be very difficult) or using a journal file with varying density and temperatures can give me accurate results for the pressure drop ?

Fluent has refprop built-in and I highly recommend it.
