Hi all,
I 've been doing a simulation of three way catalytic by importing chemkin surface mechanism into Fluent. there are two kinds of surface site in the mechanism namely Pt and Rh and there is a comment in mechanism that says the surface of composed of 75% Pt and 25% Rh. In addition, there is only one surface site density defined in mechanism file which is 2.72E-9. So my question is how can I define this site density in Fluent. my though is to define Pt site with surface density of (2.72E-9)*3/4 and Rh site with surface density of (2.72E-9)/4. Is it right? Can somebody help me? Thanks very much! weiqiang |
