I've been tasked to simulate the flow of water vapor, air, and Gas X (doesn't matter what) through a cold reservoir. The goal of this setup is to demonstrate the condensation of Gas X over a period of time 't', while the rest of the flow passes up and out of the assembly. The final goal is to be able to measure the final volume of condensed liquid in the reservoir.
I am interested to know if this type of simulation is possible in FLUENT. If so, can people provide any tips, past experiences, and point me to relevant resources to educate myself on how I can go about this task.

We have a video tutorial on evaporation/condensation process of boiling liquid using CFD in our You tube channel :'ANSYS FLUENT & CFD SOLUTION".
Please watch the below video.
Hope you will get help from the above videos.

Does the condensation happen on the wall or bulk condensation is expected to occur?

Simple condensation on the wall, would be sufficient.
September 1, 2018 at 6:16 amDrAmineAnsys EmployeeIn that Case is the Phase Change concentration driven ans you can usevthe simple Eulerian Wall Film Model to Model (Not to resolve) the condensate of vapor at Wall.

What do you mean when you say, "...model and not resolve the condensate vapor at the wall?"
Essentially, at the culmination of the simulation I need to measure the total volume of condensed volume of species X. Would this be possible given your advice?
Additionally, reading online I saw these comments on the EFM:
Ideally the model would be able to simultaneously condense both water and species X. If this is saying it cannot be condensed then should I use the Evaporation/Condensation Model?

He's on holiday.
Looking at the manual section you'd need the Evaporation-Condensation model, but you'd still need R19.2 for that as prior to that release you can only use one phase change mechanism. I'd advise checking the wall film in R19.2 too as that may also have been upgraded in the mean time.

Thanks for the update.
As I am using an Academic Student License where the 19.1 release is newest release, that means I won't be able to model this yet.
Do you know when this new release would become available for students?

did you perform the simulation? i have been tasked with a very similar peoblem

Have a look at Eulerian Wall Film, and also Eulerian (or Mixture) Model with evaporation/condenstation phase change. There have been significant advances in modelling since 19.1; current release is 2023R1, with R2 coming "soon".
