Abstract

A numerical simulation of a two-stage traveling-wave thermoacoustic engine with reducers is investigated. The results showed that the variation of different inner diameter

length

and position of the reducer affect the temperature difference and output performance of heat exchanger between two thermoacoustic engines. When both thermoacoustic engines operate under the same constant power

the reducers affect the temperature difference and output performance of the system by adjusting the phase at different positions and inner diameters that result in low-temperature difference and high energy output.
