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.
