The theoretical foundation of conventional thermoacoustic devices are the linear instability induced thermoacoustic boundary layer on the side wall of resonance tube. In the present study, we explore a possibility of new type of thermoacoustic oscillation. The results may be summarized as follows:(1) The construction of general theory which is capable of describing the cyclic phase change (evaporation and condensation) at the interface. The theory is based on the kinetic theory of gases.(2) The stability analysis of the phase-change-induced thermoacoustic oscillations.(3) The consideration of realization of new devices based on the phase-change-induced thermoacoustic oscillations.
