Prediction of the performance of the thermoacoustic engine (CoATE) using DeltaEC

Simulations for co-Axial types are carried out in two types, namely the kind where the inner tube inserted into the resonator area and the second type of inner tube inserted through the thermoacoustic core. In the first type of co-Axial simulation the acoustic power produced was much smaller compared to the kind of standing wave, while the second type of co-Axial simulation obtained higher acoustic power compared to the type of standing wave. Performance simulation on the co-Axial thermoacoustic engine (CoATE) with 25 mm inner tube diameter showed that the acoustic energy generated at 30.65 watts, 30.23 watts, 29.62 watts, 28.83 watts, and 27.85 watts for 580 mm, 530 mm and 480 mm, 430 mm, and 380 mm inner pipe, respectively. © 2020 Elsevier B.V., All rights reserved.
