Abstract
A linear dynamics model of Darcy's form for a regenerator is first derived, from which a linear network analysis is employed to study the dynamic response of the regenerator in a cyclic-flow system. It is shown that the dynamic response of the regenerator is determined by the design of the load impedance Z2(s). The amplitude attenuation and phase shift between the mass flow and the pressure wave due to the effects of the regenerator configuration and the load impedance can be clearly seen from the present linear network analysis. It is found that introduction of load impedance will reduce the bandwith of a regenerator and increase the phase lag of the mass flow with respect to the pressure wave. © 1995.
