【Abstract】 The fluid impedance method to calculate the resonance frequency and the wavelength number of thermoacoustic engines is introduced,and it is predicted that the hybrid arrangement has lower frequency than that of the double arrangement.Study on the wavelength number is instructive.Finally,the experimental results are given which verify our predication.更多还原
