Hello,

After a series of useful simulations of oil + water + some soluble components, I am now facing a task of oil + gas simulation. It is a simplification, but, as far as I understand, a more-or-less common one: water is considered immobile (hence nonexistent), gas in injected into oil; some gas gets immediately dissolved in oil, and the ratio of "gas in gas phase" / "gas in oil phase" is constant everywhere at all times. I call this an equilibrium, hoping this is the correct term. No temperature is considered.

I would be very grateful for pointers as to what DuMux models and classes I can use for this task.

Can 2p2c model handle gas? Is there an easy way to naturally write the aforementioned equilibrium into the equations? Should I deal with the fugacityCoefficient() method (which I honestly do not fully understand now) to have the equilibrium maintained?

Best regards,

Dmitry
