In the PDF document of the case" Syngas Combustion in a Round-Jet Burner", there is a mistake in the "Modeling Instructions" part, in page 13, the procedure 6th of the "Add PHYSICS", for "Mass fraction" table were in the TCS interface not in the Turbulent Flow interface, so it seemed that there is some procedure omitted in the procedure between the 4th to 6th procedure accoroding to the corresponding mph file

Best wishes,

Gao

Hi Fei,

The instructions are correct. In the Add Physics window, you are adding a Reacting Flow multiphysics interface, which includes both a Turbulent Flow (spf) interface and a Transport of Concentration Species (tcs) interface, so under Dependent Variables in that window, you can define the dependent variables for both the turbulent flow and the species transport.

Best regards,

Ok, Thank you for your advice, and I would improve my way.

Thank you for your professional advice, I have found the difference between adding a reacting flow and a spf, and I have solved the problem .
