Performance of Thermoacoustic-Standing Wave as a Power Generator

Abstract:

This study is relating to analyze performance of thermoacoustic-standing wave. Stirling cycle thermoacoustic engine is developed conventional stirling engine. This system is more efficient than ordinary stirling engine because does not use a moving piston[7]. The engine uses thermal power to generate acoustic power. It consists mainly of three parts: a thermodynamic part consisting of a stack, two heat exchangers, and a thermal buffer tube; an acoustic network consisting of an acoustic compliance and an inertance; and a resonator. When thermodynamic part heated, it will generate sounds. The sounds will flow along cylinder tube. Some aspects can be analiyzed to determine performance of tharmoacoustic-standing wave. The effect of temperature difference, stack geometry, stack position determine performance of the thermoacoustic-standing wave. Some research show that acoustic power will increase with increasing of temperature at hot heat exchanger. And optimal position and geometry of stack will generated optimal acoustic power.
