Design Analysis and fabrication of solar powered Thermoacoustic engine
Recent surge in global warming results in a need to develop more sustainable energy solutions to cater the modern energy demands. This need is greatly felt in developing nations like Pakistan but limited emphasis is put on these due to several economic restraints. A reasonable efficiency through wind power is achieved only in the coastal areas of Pakistan. Therefore, the readily available power source irrespective of geographic location is solar energy with an abundance of sunny days annually.
The thermoacoustic heat engine (TAHE) is a type of prime mover that converts thermal power to acoustic power, hence producing the required mechanical power. It is composed of a heat source and sink, some kind of porous medium where the temperature gradient is formed and a tube that houses the acoustic wave produced. Its simple design and the fact that it is one of a few prime movers that do not require moving parts make such a device an attractive alternative for many practical applications. The acoustic power produced by the TAHE can be used to generate electricity without any harmful emissions as the working fluid is an inert gas.
Hardware system – Finalized prototype will be made in working condition.
Software simulation results – mathematical analysis will be performed.
