Dear Joan,
I will try to answer briefly:
1) the tracer does not need to have thermal properties if you do not
have fluidsystem that requires it having them. So, it is your
fluidsystem that decides. It just needs to ignore the tracer whenever it
calculates any of the mentioned properties.
2) It should be enough to define a binary diffusion coefficient with
respect to the main component of the liquid/wetting phase, if the tracer
component is only in that phase
3) Setting the fugacity to 0.0 should do the job to keep your tracer in
the liquid.
4) for 2) and 3), I think the 2pncmin test should be an example, as the
salt there is also only in the aqueous phase and, as far as I remember,
this is also implemented using 3).
Best regards
Johannes

Dear DuMuX Users,
I am trying to incorporate an "inert component" as a hydrodynamic
tracer *in the 2pncNIMin model*. This tracer should only be present in
the wetting (liquid) phase and shouldn't be able to diffuse into the
non-wetting (gas) one.
A couple of questions :
1/ As the problem is *Non-Isothermal*, should this tracer have thermal
properties (such as thermal conducitvity, heat capacity etc.) and
phase change properties (Critical temperature, pressure, etc.)
/although it is physically considered not to contribute in any way/ to
the energy transfer ?
2/ Is it enough to define diffusion properties (e.g. binary diffusion
coefficients) relative to the only other component that we know is the
main component of the wetting phase, or should we define it for ALL
components present (although not physically relevant) ?
3/ Is it enough to set the fugacity of the hydrodynamic tracer in the
liquid phase to 0.0 to prevent it from "diffusing" in the gas phase ?
4/ Is there any test problem where these issues are tackled in detail ?
Thanks for your help !
Best,
Joan
