I am trying to model heat and mass transfer in a pipe flow that is opened along two screen intervals (see attached file). For that purpose I use the non-isothermal pipe-flow interface coupled with Darcy's law and heat transfer in porous media interface.
Because of the length involved, I do not want to solve heat and flow in complete 3D along borehole and I used the 1D edge element to model the heat transfer (provided with the non-isothermal interface). It appears accounting for screened intervals is not trivial. For that I used fracture flow in porous media, which is an extension of Darcy's Law for highly conductive element. It allows the fluid to go in and out from the pipe with reference to reservoir pressure.
Therefore I had a few questions : is it the best way to account for opened interval in pipe flow ? What could be the boundary conditions related to pipe inlet/outlet and fracture flow ?
Thank you for any help you can give on this issue.
Best regards.
