how can I calculate the laminar flame speed?

10 October 2014 1 6K Report

Hello,

I would like to know how Fluent calculate the laminar flame speed ? I did not find this information in the theory guide...

Thanks,

Mostafa

I think the laminar flame speed of the non-premixed model of Fluent is calculated from the PDF table using an empirical polynomial function. In the premixed (as well as partially premixed) model, the laminar flame speed is assumed either as constant, or as a user-defined function, or calculated from a relation given by Metchalchi & Keck (1982). See the attached link.
