ThermoAcoustics & Stirling Energy Conversion

Thermoacoustic phenomena occur whenever there is significant coupling between acoustic and convective-heat-transfer dynamics. Thermoacoustic instabilities occur in certain combusters, Ramjets and Scramjets, and solid-fuel rocket engines. In such devices, thermoacoustic phenomena are undesirable and sabotage proper operation. On the other hand, there are fascinating heat engines and pumps that operate based on thermoacoustic effects. These novel energy conversion devices have almost no moving parts. It is internal, high power density acoustic waves that do the mechanical work, replacing the transitional pistons, cranks and turbines.
