Carbon capture and storage

      Can we solve any carbon storage problem in Ansys?

      Probably: what problem do you want to solve?

      It depends on the process of carbon storage. Can you please elaborate on the process? Is there any phase change in the simulation?

      problem is to inject liquid co2 into geological storage such as saline aquifers and then it propagates through brine(saline water. At the time of injection, thermal effect will be on surrounding water and rocks.

      That's very feasible, but you may need a very big model. 


      Does liquid CO2 mix with saline, or does it behave like oil & water?

      Yes, I agree.


      No, liquid CO2 does not mix with saline water. It just pushes saline water to move further and trapped with minerals of rock.

      OK, then you'll need to look at porous media with VOF. If the CO2 is absorbed/reacts with the rock and/or saline you may also need to look into this. The Corey model is available for the free surface wetting, but you'll need to figure out the coefficients etc and possibly use a UDF.
