2 gas in mixture and 1 inlet 1 outlet
 

Hey, I am trying to solve gas mixture problem in comsol. I need to start inflow with one inlet, and I have gas mixture, two immiscible gas. And flow must be on one inlet through to one outlet. I looked for 2 phase models but I could not find any supporting tutorial. After that, I tried to solve this problem with multiphysics coupling. Laminar flow and transport concentrated species(TCS). But I dont guess that, It can help. Because I couldnt add two gasses into one domain. Also, TCS has 2 component but I have mixture velocity so how can I do this study ?
