Study on a New Traveling Wave Thermoacoustic Engine with External Excitation

A new external excitation traveling wave thermoacoustic engine has been designed and fabricated. With the length 1051 mm and height 242 mm respectively, the engine, which has been designed to have the maximal input of 600 W, has two external excitation and two thermal excitation, that is driven by external excitation or thermal excitation, or combination drive, This experimental facility has small size, lower onset resonance temperature and higher pressure radio, which is of great significance for introducing a variety of energies of low grade into thermoacoustic engines. This paper puts emphasis on the engine itself and the composition of the measurement system.
