Capillary geochemistry - water pressure and thermodynamics

The HP1 code incorporates modules simulating
(1) transient water flow in variably-saturated media,
(2) transport of multiple components, and
(3) mixed equilibrium/kinetic geochemical reactions.

Capillary geochemistry - water pressure and thermodynamics

Post by Marek Pekala » Fri Apr 25, 2014 9:02 am

It has been known for some time that capillary pressure can impact thermodynamic properties of water, solutes and minerals, especially under high suction conditions. I have been wondering about the possibility to account for the impact of capillary pressure on thermodynamic constants used in equilibrium calculations.

Best regards,


Marek

Hi,

there might be a feature in HP1 which I included which is able of doing that. But I am not 100% sure, and of course, it is not tested.

The thing about using capillary pressures is that it is not a very good assessment of the real situation because it lumps all the surface interactions together
just found this myself
