Hello everybody,

I am used to calculating single gaz flow but when it comes to multi-species, I am utterly neophyte.

I've been reading FLUENT manual and have some questions after that.

First, my problem, I have 2 entries, one MASS FLOW INLET of air, another MASS FLOW INLET of water vapour and a PRESSURE OUTLET.

My problems are the following :

- What should I enter in the field : Define>Models>Species>Mixture Template, knowing that I imported water vapour and air from the database? - How do I do to select water vapour and air for my 2 boundary conditions, knowing that Fluent asks me to chose between O2 and H2O only when trying to specificate the boundary condition? - What should I select as an option knwoing that I don't want any chemical reaction and would only like to simulate the exchanging of heat between the 2 gas?

Thank you in advance for answering, even partially, my questions.

After selecting any one of the available mixtures in species panel you can edit them in materials panel.If you dont want chemical reactions dont enable it in species panel.
