Hi all,
recently, I read a paper related to methane air combustion simulation with fluent. I can upload picture on CFD forum. Therefore, I can just describe the geometry here. Air and pure methane just enters computation domain throug different inlets. The author used species transport model in fluent. However, I read fluent user guide and know that species transport model is used to model molecular level mixing of species. In this case, it's obviously not a molecular level mixing according to my understanding. I am wondering why the author used species transport model instead of non premixed model. Best regards Weiqiang |

Gases always mix at molecular level until there is some mechanism present or employed to keep them separated.
