Hi
I am simulating reacting flow in a flow reactor with complete chemistry. For that, I need to provide a complete the Lewis numbers of all the species that I have in chemical mechanism.
Could anyone tell me a reliable source which I can use for Lewis number of difference chemical species, or any other suggestion on that.

Thanks Kalle for your reply. I looked into this doc before. I need a database with either Lewis number of common species or the mass and thermal diffusion coefficients from which I can calculate the Le. This doc does not have those.

Please let me know if you know any other sources.

Sure, there is all you need there... in chapter 6 you have species data that you plug in to the equations.

Mixtue averaged thermal conductivity - eq 50

Binary diffusion rate for specie: eq 3.. maybe your system contains a lot of N2, then you can let your specie diffuse into N2?
