Abstract:Thermoacoustic instability in solids paves the way for the development of solid-state thermoacoustic (SSTA) engines with superior reliability. Acoustic characteristics with respect to the performance of SSTA oscillators are investigated, where growth ratio is taken as a performance metric. Numerical analyses show that the acoustic characteristics not only determine the temperature gradient direction for strengthening the oscillation, but also affect the maximum growth ratio. A high growth ratio is obtained at … Show more
