Evaluating the onset conditions of a thermoacoustic Stirling engine loaded with an audio loudspeaker
This paper aims to evaluate the onset conditions of a thermoacoustic Stirling engine loaded with a commercially available audio loudspeaker. The thermoacoustic engine converts supplied heat power into mechanical power in the form of sound, without any ...
