Hi, thank you very much for providing the forum :)
Is there any example about "multiphase (CO2-Water) flow in porous media coupled with reaction".
in the website there was a modeling work by "Elena Abarca" on "Modeling CO2 migration in a saline
aquifer". Is that work accessible for us? And is it possible to couple the reactions to that work? As I see the work is done without including the
reactions.

Hello, welcome to iCP forum!

At the moment iCP is not able to simulate multiphase processes. However, we are working on the development of reactive multiphase models and we hope to incorporate these capabilities in a future version of iCP.

The iMaGe blog is a platform to disseminate the key aspects of geoscience models in a short format. It is thought as a broad platform, so you can find models not performed with iCP. The post you are referring to will be soon published in a scientific journal with more detailed explanations. We can keep you informed of its publication if you like.

Hi Rohaldin (and all),

Just some adds to the post by Álvaro.

iCP can be used for solving multiphase flow and reactive transport problems, but what Álvaro meant (I think) is that iCP does not include a stand alone physics interface to solve the multiphase flow. It is the user that must formulate and introduce the physics into Comsol. In order to make a consistent implementation of the reactive transport system, the user must incorporate a miscible formulation of the multiphase flow. Then, Comsol will compute the gas partial pressure at every time and every node, an then iCP can pass this information to Phreeqc for the chemical calculations. This should work well.

But you are right Rohaldin, we have never used this capability in iCP (so far) and the example posted in the blog by Elena does not include chemical processes. Actually, our colleague Álvaro is performing his Ph.D. dissertation on that particular subject (reactive transport modelling in multiphase flow conditions), and we hope he will (and we are pushing him) publish on that topic soon!!

As Álvaro said, we plan to develop a multiphase flow physics interface to be distributed within future versions of iCP (but I do not think that will come before summer 2015).

Best
