Understanding and application of thermoacoustic phenomena


Acoustic oscillations of a gas column in narrow flow channels can lead to various thermal phenomena such as production and amplification of acoustic power from heat and generation of low temperatures. We aim at understanding these thermoacoustic phenomena from experimental point of view, and developing heat engines that can operate without any moving parts like solid pistons.

Targeted Application(s)/Industry

Acoustic prime mover can use various heat sources like industrial waste heat and sunlight. Acoustic cooler is a Helium-gas based heat pump that needs no Freon gases as a coolant.
