Theoretical and Experimental Study of Thermoacoustic Engines
Abstract
This report describes theoretical and experimental research on thermoacoustic engines. The work includes three principal components: (1) theoretical and experimental work performed at the Naval Postgraduate School, (2) theoretical investigation of the thermoacoustic engine from acoustic analysis rather then energy analysis, (3) and design of a low frequency thermoacoustic driver utilizing square pore material for the stack. An acoustic based theory was conducted to predict the onset of oscillation in a thermoacoustic driver and for the Q of the resonance and performed measurements. The experimental results agree, well with the theory. An acoustic theory for thermoacoustic engines utilizing various stack geometries was developed. this theory was based on earlier work on sound propagation in arbitrary pore shapes. A thermoacoustic driver was designed based on the square pore theory.
