Experimental review of a travelling-wave thermoacoustic system device

Abstract

Abstract The thermoacoustic travelling wave device system has been designed and we have tested, this thermoacoustic device consists of loud-speakers as a sound wave source with a capacity of 120 W, branched-tubes resonator, and loop-tube resonator that have a regenerator with a length of 8 cm placed inside loop-tube. Regenerator is made of acrylic material which has a size of 1 mm and the distance between pores and other pores also has a distance of 1 mm. The performance of the thermoacoustic travelling wave device is observed from the temperature changes it has and is reflected in how much changes in cold reservoir temperature and hot reservoirs it can achieve. The results of the experiments obtained will be analyzed in the form of temperature charts showing temperatures in hot reservoir and cold reservoir as a function of time. The temperature difference between the two sides of the regenerator reaches 26,3°C with details of the temperature rise of the heat side of the regenerator (Th ) up to δTh = 13,4°C and the temperature drop of the cold side of the regenerator (Tc ) down to δTc = 12,9°C.
