Abstract

We couple a dynamic, fully implicit non-isothermal two-phase, two-component pore-network model (PNM) to a free-flow domain where the single-phase flow Navier-Stokes equations with component and energy transport are solved. A monolithic coupling scheme guarantees the conservation of mass, momentum and energy across the coupling interface and allows solving the system without any coupling iterations. We present a numerical example and show that the model is able to temporally resolve the pore-local flow and transport dynamics of an evaporation process.
