Helo.

Please help me to understand.

What difference between mixture fraction (in U_guide wrote "mixture fraction of the leading reactant") which set in panel "Reaction System" and mass contsentration of Fuel (c7h16) which I set in panel "Scalar Boundary" in inlets?

I have one reaction C7H16+11O2->7CO2+8H2O. I assume "Premixed" type of reaction, model "Ebu standart", "Local Source".

What is mean leading reactant? C7H16? What is mean mixture? 1) The whole mix (with N2 and other) or 2) just C7H16+ 11O2

If the first variant right and I assume stoichiometric combustion, then mixture fraction will equal mass contsentration of C7H16 in Inlets

P.S. Our suppoter can't answered me this question, just send me additional combastion tutorial.

I will thankfull for all answers.
