Abstract

A thermoacoustic system gives a lot of benefit to the environment and the ecosystem. A thermoacoustic system helps us to reduce pollution and fully make use of the sound energy that been wasted before. Even though the thermoacoustic system is a good technology but without fully understanding how it works and the elements that affect the thermoacoustic system’s efficiency, it just a waste for us. Therefore, a study of wave distortion allows us to understand the wave behaviour of the wave that been used in thermoacoustic. Besides, additional knowledge on other elements may help increase the efficiency of the thermoacoustic system. In this study, two mini test rigs of the thermoacoustic system have been made to measure wave velocity experimentally. The mini test rigs are differed by diameter and length of the resonator. We could understand the relationship between the wave velocity, diameter, and the length of the resonator from the findings. It is found that wave distortion has existed in the design of a small diameter but long resonator.
