A numerical analysis for the fluid flow and heat transport phenomenon through a rotary thermal regenerator is presented by means of employing the porous media concept. An aluminum core formed of multi packed square passages is simulated as a porous medium of an orthotropic porosity in order to allow the counter-flowing streams to flow in a way similar to that inside the regenerator core. The geometricproperties of the core were transformed into the conventional porous media parameters such as the permeability and the inertial coefficient based on empirical equations; so, the core has been dealt with as a porous medium of known features. Local thermal non-equilibrium situation is assumed between both fluid and solid phases, so heat is allowed to be exchanged between them. The results are presented by means of overall temperature effectiveness, pressure drop, and the relative output power. The use of porous media approach has been found to besufficient to solve the current problem. The data obtained reveals an obvious impact of the core geometrical parameters on both the heat restored and the pressure loss; and hence, the overall efficiency of the regenerator system
