Simulation of coupled flows in adjacent porous and open domains using a control-volume finite-element method

A control-volume finite-element method is used for simulations of flows through coupled fluid-saturated porous and open domains. The Brinkman-Forchheimer equations are used to model the flow in the porous domain. Modeling at the interface is emphasized, and full consistency is ensured. No special modifications need to be implemented in the numerical procedures and computer codes developed to deal primarily with flows in open domains, the interface conditions being treated in a consistent and natural way. Three illustrative examples involving flows parallel to the interface, flows normal to the interface, and combined parallel-normal flows are presented.
