Hai,

I have to model two gas mixing (air and ammonia).

Which standard solver do I need to select in openfoam.

These gases are mixing in T juction. Air inlet pressure 5 bar and temperature 600K. Ammonia inlet pressure is 6 bar and temperature 650K.

This model need to develop for gas mixing without reaction.

Please reply any of you know the required model for this case.

Best regards,
Prasanna.

Hi All,

I am working on a ventilation project, in which a source of gas is placed in a room. The gas is Ammonia. The source details ex. emission rate is known.

I am trying to simulate this, but not able to select the appropriate solver. Passive Species modelling may not help I think as the Ammonia has lower density than air and the emission rate is really low. So the gas may rise due to gravity.

I have simulated the passive species transport previously. Please guide in selecting the proper solver.

Thanks

Here is a post where I suggested using rhoReactingBuoyantFoam with the reactions off.

Hope this helps.
