Abstract
Over the past several years, much interest has been devoted to the study of thermoacoustic machines that have the simple construction and do not use the ozone depleting fluid. It is important to understand the thermoacoustics characteristics for developing thermoacoustic machines. This paper is concerned with analyzing the detailed behavior of thermoacoustic machines by using a numerical cycle simulation. Complete differential equations of continuity, momentum and energy of working gas, as well as energy of stack and heat exchanger walls are employed as the governing equations. The experimental results are also discussed to confirm its validity. In this report a typical thermoacoustic generator is adopted.
