Abstract :
Characteristic impedances of regenerator and heat exchanger in thermoacoustic engine are analyzed by network model. The effects of regenerator geometry on characteristic impedance of regenerator are studied. The characteristic impedances of regenerator and heat exchanger which have same structure are calculated, the result indicated that the absolute value of the characteristic impedance of regenerator is lower than heat exchanger because of thermoacoustic effects of regenerator.
