Species transport
Hi guys...
I want to model fire with the mass fractions of oxygen and nitrogen. I can add the mass fraction of oxygen by default and the row for mass fraction of nitrogen is not available. To add the nitrogen row, I have to add air and I can put the nitrogen mass fraction as well. But, when I start the simulation, the error comes up saying that "Error at Node 27: Species air not in thermo database" Can someone please help or suggest me something? Thank you. Best regards, Ritesh |
Hi,
Nitrogen is the bulk species(last_species), so it will not appear in species tab but it will consider the rest of the mass fraction.for example if you give 0.21 for oxygen then that bulk species will consider 0.79(i.e,the rest mass fraction). |
