I calculate mixture fraction using Bilger's formula in OpenFOAM 2.3.x, as here:

https://github.com/adhiraj-dasgupta/...ixtureFraction

Maybe you can use this utility as a guide?

Dear Adhiraj

First of all thanks for the reply and the code.
I have implemented the mixture fraction formulation onto OpenFOAM code.

But now I want to add the conserved equation of the mixture fraction in the code, can you help me for that?

It should be easy top add an equation for mixture fraction (just a passive scalar), unless I am missing something.

Can you provide more details about what you are trying to implement, and if you are running into any errors?

I want to add this particular conserved mixture fraction equation (without closing term) by replacing the species conservation equation.

This looks straightforward to implement. What errors did you get?

as I told by replacing the species conservation equation
, so how to make it possible that is the main thing, means directly we need mixture fraction

There are tutorials available to add an equation for a scalar in OpenFOAM. For example, see here:

https://openfoamwiki.net/index.php/H...perature_field

Study this and then adapt it to your needs.
