Experimental Investigation of Thermoacoustic Refrigerator with Direct Cooling

Abstract

Experimental investigation on blowing-out phenomena of cooled air from the thermoacoustic tube was made with and without high temperature heat exchanger. Although all the instruments was made in fully air-tight, the air blew out continuously from the tube. The flow rate of the air increased with the distance from the outlet hole to the inlet of the measuring tube. The flow rate also increased with the increased of the diameter of the measuring tube.
