Abstract
Much effort has recently been devoted to study thermoacousitc machines that have the simple construction and do not use the ozone depleting fluid. A numerical simulation is essential to understand the thermoacoustic characteristics. We are developing a numerical simulation model with a view to analyze the detailed behavior of thermoacoustic machines. 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 thermoacoustic generator of typical standing wave type machine is adopted as the analyzing target.
