Hi everybody i want to reproduce the problem "Syngas Combustion in a Round-Jet Burner" with comsol 4.3, this problem has been solved with comsol 4.4, but ! I don't know how to couple reacting flow with turbulent flow, someone can help me??

Hi,

Do you want to make is on version 4.3, not 4.3a or 4.3b? Version 4.3 doesn't include reaction rate model with Eddy Dissipation model which is needed in this model. This was introdused in version 4.3a.

If you want to do in 4.3, you will need to combine "Transport of Concentrated Species", "Turbulent flow" and "Heat transfer in fluids". Also you have to make reaction rate by Eddy Dissipation model functions.

Best regards
