Can different gas flow rate consturct in global model?
 

Hi all,

I am constructing a 0D global model of Ar/CH4/H2, by referring to this paper:https://www.researchgate.net/publica...nanostructures

Inside the paper it mentioned that, the flow rate of different gaseous is varied differently. However how am I able to do this in a global model?

You can put only one flow rate and put (mass or molar) % for each inlet species.

Yes, seems like in this case you only can define the ratio of inlet gas instead of specific flow rate. For example, Ar/CH4 (0.9:0.1) with one flow rate of 1000sccm.
