The characteristics of the periodic pulsatile flow in a regenerator was experimentally studied with flow periods and mesh numbers of regenerator packing materials. The regenerator test system which can generate periodic pulsatile flows with various periods was constructed. The pressure drop and the volume flowrate of the pulsatile flow in the regenerator significantly depends on the periods and the porosities of the materials. The pressure drop are decreased as the period of the pulsatile flow and the porosity of the packing material increase.
