Hi Austin:

Closed Homgeneous batch reactors are intended for homegeneous processes, so there is no spatial component.  To add a spatial component to the combustion, a different Chemkin model is required

2.3.5. Burner-stabilized Flame

Flame propagation in Chemkin can be done using the Flame Speed Library Reactor model. 

2.3.9. Parameter Study: Propane/Air Flame Speed as a Function of Equivalence Ratio and Unburned Gas Temperature

 

This allows you to plot species change across the flamefront:

Both are diffusion flames.  Flame propagation is fundementally a 3D process, and should be modelled with rull CFD.  Chemkin can be used to generate the required flame library information to make the CFD calculations accurate, however.

Best Regards,

Judy
