Hello,

I am looking at doing a validation for my combustion model and i wanted to know how I could display the flame front (so i can get flame length and width) from the species fraction model? I am using the species fraction model to model the combustion

Intuition is nice but to come up with a quantitative definition for things is tough. The problem is the governing equations are not written in terms of where the flame is, but in terms of conserved quantities: mass, momentum, energy, etc. This is like the boundary layer thickness problem, but more complicated.

First you have to define what the flame front is in terms of the variables that you have.
