| Abstract: | The behavior of thermoacoustic waves in a helium-filled standing-wave prime mover is numerically studied. The thermoacoustic equations have been developed for the calculation of time-averaged energy fluxes for devices operating at low pressure amplitudes. Here we present details for a thermoacoustic calculation method, shooting target method, for standing-wave heat engine. A large thermoacoustic engine is studied as a case study. It is showed that the code can run well for most operating conditions of interests and output whatever results the user is interested in, typically temperature, pressure amplitude, impedance, and acoustic power at various location, and operating frequency. |
