Abstract

Basing on the analytical passive network modeling on the flow characteristic of an isothermal regenerator proposed before, an active network modeling for the regenerator with temperature gradient has been established proceeding from the progress of the theory of thermoacoustic refrigerator. The active source term of the modeling has been discussed. The thermally induced acoustic effect occurring in a regenerator with temperature gradient has been experimentally verified on particularly built regenerator experimental set-up.
