Sondhauss and Rijke oscillations—thermodynamic analysis, possible applications and analogies

The phenomena of acoustical pressure oscillations generated in a gas by a steady heat source may be separated into two distinct types: (i) Sondhauss oscillations which occur in a pipe having one end closed and one open; (ii) Rijke oscillations which occur in a pipe with both ends open. After reviewing representative literature, actual and possible applications are described. Analogies and differences among these and similar systems are considered from a thermodynamic point of view.
