This work presents the formulation, verification, and application of an OpenFOAM- based multiphase solver for physical systems with moving and stationary phases. The latter is used to model porous media, allowing for the simulation of multiphase flow processes applied to many areas of science and engineering. The model considers an implicit coupled solution of the phasefraction equations for an arbitrary number of phases in the system, providing better approximations when compared to the standard segregated solution. We present verification tests simulated in scenarios with different numbers of moving phases, along with an application case.
