modelling of flow between methane and air
 

hi!!

is it possible in FLUENT 5.4 to analyse the flow between two fluids (methane and air) without any chemical reaction. i tried to use injections but in that methane is not mentioned...plz help me

bye satya

i am also trying to do methane - air combustion, however since ihave to analyse natural gas combustion, i am using partially premixed combustion model (since NOx models are not available with premixed-combustion models). well you can try partially premixed model also, for methane and air.

use species transport, and define your mixture components in the material-panel.

Hi, I'm a newbie in Fluent but I believe that you can use the Eddy Break Up Model. Is it available on the code, right? Well, once you've set up your problem find out a way to set the A constant of the reaction rate (which is function of turbulent parameters) to zero. Then you'll have a null reaction rate giving you no products. This may work.
Good luck, cfd guy

and if you are still not able to do it

drop me an email, i will send you relevent files and instructions in detail to model it.

thanks

wanted
 

Plz can you send your relevant files and instruction in detail to model it to this email "talkh2005@yahoo.com"
