The operation frequency dependence of the performance of a Stirling engine was examined in a wide frequency range employing a simulation code, THERMOACOUSTICA, based on the thermoacoustic theory. Results of the simulation were roughly in accordance with expectations. For example, the results satisfies both the first and second laws of thermodynamics. The efficiency and the output work depend on the operation frequency. The frequency corresponding to the maximum output work is considerably higher than that corresponding to the maximum efficiency. The temperature distribution in the regenerator is also dependent on the operation frequency.
