Hi everyone, 

I am trying to calculate the laminar flame speed for a SI engine using Chemkin Pro (version 2022 V2). I'm a SI engine closed reactor (this can be simulated as the one I have in my lab), but I can not find the variable (the laminar flame speed) in my results. I'm aware that there is a flame speed calculator, but I don't want to use a freely propagating flame. The spark ignition part is really important for my further study. 

 

Thanks in advance

Hi Paul: 

Only the flamespeed calculators will offer flame speed as a variable.  There are several types of flames.  The premixed laminar flame speed library or calculator are the most appropriate, depending on whether you need  a range of flamespeeds for different mixture fractions, or a single value for a premixed calculation.

 

Best Regards,
