Non-premixed Combustion
 

Hi Fluent users,

I would like to know if I have 2 streams of air, 1 dry air and 1 moist air (ie include H2O component in my mass fraction), is it possible to use the non-premixed combustion? If I can, how am I going to define the compositions of the 2 different air streams at the inlet boundaries since the boundries ask for 'mean mixture fraction' and 'mixture fraction variance'.

Please help!!

You can use the specie transport and the eddy dissipation model. In that case you can specifie individual species on any boundary Jan

Or you can use the two-mixture fraction model.
