How to define the mixture of air and other gas?
 

I wanna compute the mixture of air and N2, but could not excute Multiphase order in Fluent, what can i do? there is no chemical reaction in this flow. thanks

I fail to see the problem. Why do you need Fluent to calculate the mixture composition of the air/N2 mixture ? Isn't that done easily by hand ?

My research is about interaction flow of lateral jet in supersonic exterior flow.

Oh. That may be hard and time demanding to do by hand. Guess I misunderstood your question. My bad.

I suppose you should try species equations instead of multiphase models.
