Burner-stabilized flame documentation

[Irfan Mulla]

Hello there,

I am simulating burner-stabilized flat flame (McKenna burner), for which boundary conditions are

1) mdot (mass-flux, kg/m2-s)

2) tburner (burner temperature, K) at z=0

3) Species mole fraction in fresh gas at z=0 (fuel/O2/N2)

I am using "BurnerFlame" command in Cantera. 

Species diffusion: At the end of simulation, it appears that there are many other species (other than fuel/O2/N2) at z=0, which I learned is normal due to species diffusion back into the burner face. There is a discussion on this in Kee et al. text book, some of the pages are attached here. 

Question: what exactly is the species boundary condition respected here (fuel/O2/N2 mole fractions are clearly not respected)? Is it somewhat similar to Kee et al. explanation?

Temperature: The temperature is quite lower than adiabatic flame temperature, which is not surprising as the burner stabilized flame is non-adiabatic. 

Question: How is the heat transfer modeled? Any theory? 

If any of you know the documentation (or a journal article) by which the burner-stabilized flame is modeled in Cantera, that would be rally helpful. 

At this stage problem description is quite brief, if you have any specific questions do feel free to let me know. Looking forward to hear from you. Thanks!

Regards,

Irfan
