Abstract
Modeling the interactions between a porous flow and a plain one, especially for ablating materials, is complex. The current state-of-the-art models use simplified assumptions at the interface. A unified approach that solves both domains at the same time is developed in this paper. The solver adopts a universal system of equations that covers plain and porous flows with reactions. The solver is verified through analytical problems and two benchmark channel flow problems. Moreover, the developed solver is validated through two series of flow tube experiments.
