Two kinds of gases in general mode

[juntao pan]

Hi all,

Does PFLOTRAN support two kinds of gas in general mode? I want to inject CO₂ into soil that is not initially water-saturated, so that CO₂ can diffuse and mix with the original air inside the soil. How can I achieve this?

Best,

Juntao

PFLOTRAN does not support mixtures of gas component (i.e, > 1 gas component) on the flow side. The code does support multiple gas species on the transport side. I would define a CO2(g) species on the transport side and allow it to convect/diffuse in the gas phase within the porous medium.

 

Note that by default, gas mass is not transferred between the flow mass conservation equations and the transport mass conservation equations.
