Non reactive mixture problem

idil · January 28, 2013, 04:58

Hello,

I am trying to simulate a coupled microreactor. There are two channels parallel to each other. in one channel there is a reactive mixture flow. In the other channel there should be a non reactive mixture flow.
I am using Fluent 14.5. I created the reactive mixture and I set all the reactions in the Metarials section. But when I try to set another mixture template, program automatically assign it as reactive. It wants me to set at least one reaction.
How can I create the second non reactive mixture, any idea?

Thanks in advance,
idil

If they are separate cell zones, then you can go into "Cell Zone Conditions" and disable the reaction on a per zone basis.

Thanks for your reply. It is true they are seperate zones. I tried to assign the second mixture (nonreactive one) to the related zone from cell zone conditions part. But it doesn't appear in the materials list. Do you have any idea why it happens that way?
