Abstract
Thermoacoustic engines convert heat energy into pressure amplitude sound waves, that is used to drive bidirectional turbine by replacing streaming fluid flow such as wind turbine. The increasing interest in thermoacoustic technology of its potentiality of no exotic materials, low cost, and high reliability is compared to mechanism wind turbine system. The simulation set up in Delta EC has been built based on the linear thermoacoustic model and simple design parameters. The engines produce acoustic energy at the temperature difference of 315 until 993 K imposed along the stack of the system. The work illustrates the influence of porosity of stack wire mesh screen with resonator length on the acoustic power of thermoacoustic engine using air as a working fluid. That can be infered in the results obtained from the simulation are in good agreement with the theoretical result from an experimental study.
