I am trying to replicate the results obtained in the attached CFD Simulation journal article.
Following is the information from a journal article I could infer and specify in fluent software.
Gas: N2 (density 23.4, viscosity 1.77e-5)
Liquid: Naptha (density 702.3, viscosity 3.59e-4)
(The two materials are not natively available in the fluent database and hence I used the existing materials to change the values. I hope density and viscosity are the only two values fluent uses.)
surface tension 0.0185N/m
Dia of pipe 189mm. L/D = 30
Liquid/gas superficial velocity= 0.05/0.1 m/s
Model type : Eularian Eularian Multiphase VOF with 2 phases
There are two separate inlets for liquid and gas.


I have kept everything constant/default. I was wondering What I did wrong as I could not replicate the results from the paper. which have bubbly flow?

The file can be found at link
https://www.onepetro.org/conference-paper/OTC-24245-MS

Any help would be appreciated

edit: attached the results image from journal article.

Very, very hard to tell what is wrong with your results, since you're only showing some pretty pictures from a journal that has a pay wall. MY guess is you will get little resonance here, so try to be more specific about what a) you have done in your simulation and b) how you results differ from the expected results.
