Effect of heat loss ratio dimension on FGM table

I am performing a RANS simulation of a turbulent premixed flame, with an isothermal wall set at 600 K. To simulate the flame, am using the FGM method with progress variable, mixture fraction and heat loss ratio as controlling variables. I am comparing my results with a simulation that does not include heat loss ratio in its flamelet tabulation and underpredicts peak flame temperature.
I want to better understand why the inclusion of heat loss ratio in the table results in a better prediction of peak temperature. My understanding so far is:
Is what I'm saying correct? I think there's some gaps in my understanding, particularly with the effect of different heat capacities on how temperature is obtained by the solver accessing the table, near and away from the wall. Thanks for any help you can give! |
