“…Thermoacoustic is a study of the field of interaction between heat and sound, namely about the conversion of thermal energy into sound energy (acoustic) and vice versa [3]. To produce thermoacoustic effects, thermoacoustic devices are needed [4], namely the thermoacoustic engine (prime mover) [5], [6] and thermoacoustic cooler [7], [8], which is often referred to as the heat pump [9]. Several studies have been conducted to improve the efficiency of the performance of thermoacoustic engines.…”

The thermoacoustic engine can be a device to convert waste heat energy in the engine car become useful energy such as for charging battery in car or Air conditioner of the car. This work can be done by experimentally and numerically. There are some parameters that have an impact on the performance of the engine. They are geometry of the engines, working fluid, and mean pressure. The performance of the engine depends on the efficiency and the heating temperature. In the car, waste heat energy is not high enough. Therefore, we need to utilize the low heating temperature to be converted into useful energy. This study contributes to numerically the effect of mean pressure and loop’s radius of the regenerator on the onset temperature and the efficiency of traveling wave thermoacoustic engines. The application that is used to solve numerical problems is fortran95. There are two codings that are used in fortran95. They are stability limits and efficiency codes. The lowest onset temperature that achieved is 153˚C with efficiency up to 38.1% that can be reached when the mean pressure is 4.0 MPa and the loop's radius is 5 cm. This result indicated that we can use low heating temperatures from waste heat of engine car to turn on electronics equipment inside the car.

“…Likely, in 2020 Farikhah did the numerical calculation and got the results that the efficiency of the engine is 75%. However, the onset heating temperature is 307 ℃ [8]. Experimental research and numerical studies have been carried out to obtain the lowest onset temperature and highest engine efficiency.…”

In order to develop and increase the performance of a thermoacoustic refrigerator system, a research has been conducted. In this research a PVC cylindrical pipe (diameter of 5.5 cm and length of 80 cm) as a tube resonator, a loudspeaker as a sound source, some stainless steel mesh as a stack and a hot heat exchanger were arranged to be a thermoacoustic refrigerator system. The results show the influence of cooling power by utilizing some stainless steel mesh stack, the power of the utilized sound, and a hot heat exchanger on the performance of the thermoacoustic system. We expected to construct a thermoacoustic refrigerator system, which has an optimally performance, by using some stainless stell mesh as stack and a hot heat exchanger.
