“…According to previous research, which was conducted by experimental method, the result has the same trend as this simulation method. The longer the resonator length the smaller the value of acoustic intensity (Anugrah et al, 2018). So, the acoustic intensity is reflected how much the acoustic power is because it is represented by the power divided by cross-sectional area.…”

Many applications of thermoacoustic engines in engineering. With its pressure of it, the energy can be harvested and can be converted to many other needs of energies like electrical energy. Energy in thermal form is converted to become acoustic energy and subsequently used to activate a bidirectional turbine. The resonator is very influential toward the power of the thermoacoustic engines. Simulation study with Delta EC fit to make predictions acoustic power as representative performance in thermoacoustic engine with close-open type and standing wave of oscillation. In this study, the material of the resonator is made from a stainless-steel duct with a diameter size of 50.8 mm with three variations of the length. The Standing-Wave Thermoacoustic Engine (SWTE) generates acoustic energy from a temperature gradient of 315 – 993 K. In this simulation, Acoustic Power decreased when the resonator length was extended. The shortest resonator had an acoustic power of 50.4 W, and the longest resonator had an acoustic power of 35.7 W.

Tilted angles have to be researched for determining the good position of thermoacoustic engine. The research aims to find the best acoustic power with a tilted angle of the position, therefore the performance of Standing-Wave Thermoacoustic Engine (SWTE) is going to be increased. The performance is affected by the tilted angles. The natural convection which occurs in the core of Themoacoustic Engine will be different every tilted angle. The heat transfer characteristics within it were investigated under three tilted angles including, -90°, 0°, and 90°, with the resonator length 780 mm. This study was for getting the acoustic power which used the two sensors method with Data Acquisition (DAQ) NI-DAQmx 15.5 and two pressure transducers. It was calculated by Matlab R2013a. In this research is found that the acoustic power which is the best value is resulted on 90° of tilted angle, while the smallest value is found on 0°. Thes matter can be occured because phase difference of acoustic wave on the 90° is the biggest value, while the 0° is the smallest value. Further, have to study how phase difference has big effect toward the horizontal position which is resulted on the worse value compared the vertical position.
