Hello,

I am new to both Fluent and this forum, so please forgive my lack of familiarity with the software. I have worked through the applicable tutorials on the customer portal, listened to some of the webinars, and have searched extensively on this forum, but I can't seem to figure out how to setup a simulation I am working on.

I am modeling a situation where I have a glassware tube with a flow of hydrogen coming into the bottom port, a flow of argon coming down into the top port, and both gasses are exiting through the side port which is at atmospheric pressure.

Please see the attached image of the geometry/mesh that I am working with. I have employed symmetry and have created a 'named selection' for each of the inlets, the symmetry plane, and the wall group.

My main question is how do I specify the different fluids coming into each of the ports? I have been assuming that I need to use a multiphase model, and have been trying to use the eulerian model but haven't been able to put it all together. Also, I am assuming that I need to define the cell zone conditions, but I don't know what the composition of the cell zone is going to be as the two flows will be interacting.

Also, I would like to create a ~200mm zone below the side port which will model a furnace surrounding the glassware. I am assuming that I need to create a different wall group for that section and just create a temperature boundary condition with the energy model turned on?

Thanks much for any help,
