Small thermoacoustic devices can fulfill a need for high-performance compact energy conversion systems. One of the miniaturization consequences is the appearance of strong transverse temperature gradients in the stacks of thermoacoustic engines. The thermoacoustic theory is extended in this paper to include a transverse gradient of the mean temperature field. The influence of this gradient on the acoustic velocity and temperature fluctuation amplitudes and on the flow of thermoacoustic enthalpy and acoustic energy is demonstrated under the standing-wave conditions and in the absence of mass streaming.
