mixture fraction method for non-premixed flame

Habibfateh · August 2, 2014, 07:46

Hello my friends

I have a question!
How can I use mixture fraction method combustion model in reacting Foam solver?
Is there any subroutine that I can add it to reacting Foam solver?
Please help

thanks a lot.

Hello. If I understand, mixture fraction method is a method where all the components of the burned mass are traced all together as if they are the single complex substance. One can realise this method by using the simple chemical reaction. The only condition is the mass of the product of the reaction is equal the mass of your complex substance.
After computing one can find the needed specie (component) ratio by using the calculator of the ParaFoam.

Hello,

There is a steady flamelet solver for OpenFoam-2.1.0, you can find it here:http://openfoamwiki.net/index.php/Ex...n/flameletFoam.

And you can also find lot a information about flamelet model for OpenFoam here:http://www.cfd-online.com/Forums/blo...-openfoam.html

Best,
