摘　　要：采用一维平均化的方法建立了热声制冷数值模型，该模型可应用于线性和非线性范围。运用该模型对热声制冷的机理以及相对波动压力和平均充气压力对热声制冷性能的影响进行了分析。A one-dimensional numerical model of thermoacoustic refrigeration is developed through integration of the governing equations over the cross section of the resonator. This model can be applied to linear and non-linear regimes. Using this model, the paper analyzes the priciples of thermoacoustic refrigeration, and subseqently discusses the effect of various operating parameters, such as mean pressure and diver ratio, on the performance of thermoacoustic refrigerator.
