Mixture at the inlet in air domain
 

Hello,
I am currently modeling a 2D nozzle and its exhaust plume in fluent. I would like to simulate this with the products of the combustion flowing from the inlet (end of the combustion chamber, which is an edge as this is a 2D problem) while the fluid domain is the ambiant atmosphere (air). By using the mixture-template, I can set the products at the inlet but it seems that i cannot asociate this setting with a domain filled with air. Does someone have an idea ?
Thank you for your answers!

Hello

Have you seen the tutorial files provided by Ansys? Their example is similar to what you described your model to be.

If this is still a problem, can you share some images of the mixture template and boundary condition of the problem area?

Regards

Thank you for your answer! I didn't see these files, however I found a way (confirmed by ANSYS forum administrator) to deal with this. By adding air as the last element of the mixture, I can initialize an air inlet with the other components set to 0 and the mixture inlet with the desired mole fractions. And it seems to work!
