Mixing of two different gases
 

Sorry in advance for the newbie question!

I am a student attempting to run simulations that focus on the mixture of a gas and air across a pipe producing a free jet into the atmosphere. I have come to the part where I need to define the source of each gas.

How would I accomplish this? Do I need two different physics models, one for each gas at each inlet? If there is a helpful tutorial in the program you could direct me towards, I think that could be a big help.

Thanks!

Hey Man
Did you figure it out in the end?
I am doing something similar and would appreciate any help.

Thanks
