Abstract:
The construction of a thermoacoustically (heat) driven, thermoacoustic refrigerator (TADTAR) is nearing completion. The design utilizes a novel resonator topology and high-efficiency primary heat exchangers. Numerical models suggest a cooling power level of at least 500 W over a temperature span of 40 (degrees)C. The design should be easily scalable to much higher cooling power levels. Experimental data characterizing the prime mover portion of the engine will be presented, possibly along with some preliminary refrigeration data. [Work supported by ONR.]
