Temperature is abnormally high!
 
I try to simulate the process of combustion between two infinite parallel planes. I can't explain why the maximum temperature is abnormally high.

I have considered the relationship between the thermal capacity and the temperature.

What kind of combustion model do you use? I find the same hapenning with a one-step reaction with finite-rate kinetics. But that might be the limitation of doing finite rate kinetic modeling.

I have tried:

Segregated Solver\Unsteady 1-st-Order Implicit

Viscous Modle \ K-e

Species Model\Specise Transport Volumetric Recation\Laminar Finite-Rate

And I have considered the relationship between the thermal capacity and the temperature.

What the other attention I should have to pay to?

Should I have to consideration Radiation Model? I"m going to try to add this model!

Hi, I want to know how did you simulated infinite plate,you have used laminar flame model,is your flow is in laminar region,did you get any help by including radiation.
