Abstract A hyperbolic system of partial differential equations based on the volume averaged Navier Stokes system is discretized and used to portray the fluid and matrix interactions during oscillating regenerator flows. This system is solved using the Method of Characteristics for axial flow and time for the fluid phase while the matrix energy balance is solved using a discretized Fourier conduction equation axially and in time. Solution of the fluid phase is simplified by integration of the microscale diffusive flow friction and dissipative energy balance effects using volume averaging principles. The solution then uses a solution grid which is of the same order size as the volume averaging integration volumes. Correlations between previously obtained empirical regenerator performance data and these solution results indicate that this modeling approach appropriately describes the macroscopic performance character of a real regenerator.
