How to simulate the influence of an air flow on another?

Hello.

I'm completely new to Flow Simulation and despite having spent a day reading the online tutorial and watching examples on YouTube I'm having trouble extrapolating to my study case.

I need to be able to see the influence of an air flow on the other, something similar to the sample print-screen here.

We have air flowing through the flexible coolant at an arbitrary rate and argon flowing through the container next to the coolant at a 13L/min.

Can someone please give me some guidance on how I can simulate this?

Thank you in advance!
