Question about " Laminar flame speed - Pressure dependence of flame speed when pressure is less than 1 bar"

[rdwor]

Hello everyone,

we all know that the laminar flame speed pressure dependent. I stumbled across something in Cantera and I'm wondering if FreeFlame somehow factors out the pressure dependency in the low pressure calculation, or if the assumed influence of pressure in the simulation of certain fuels is not that significant.

Composition of gas used for the calculation is alike NMC in Air 1:3 (see https://www.researchgate.net/figure/Composition-of-gas-generated-inside-the-NMC-graphite-cell-identified-using-gas_fig6_395990098) 

Plot looks like https://groups.google.com/g/cantera-users/c/tohqdIbYZ_Y/m/HcO4e7bSAAAJ -> adiabatic temperature same / Su the same - only the position of the peak change if a run the simulation at 1 bar, 0.5bar and 0.2bar.

Thank you for your efforts.

Regards, René
