中文摘要：
提出了可压缩流体交变流动下回热器的新模型，利用所得的热声热粘函数fκ、fμ的一般简化式，获得影响回热器特性的普遍关联式。根据回热器内流场与温度场分布相似的假设条件，通过简单的双传感器测量方法，得到回热器内的小Reω下的流动阻力与对流换热系数。
英文摘要：
A new linear model on the flow and heat transfer in oscillating flow regenerator is introduced. Based on the thermoacoustic functions fκ, fμ of simple ducts, general expressions for fκ and fμ for arbitrary shaped pores are deduced. By applying the general expressions of thermoacoustic functions to the porous media constructed regenerator, the flow and heat transfer characteristics can be measured simply by using pressure transducers. Roughly assuming that the velocity and temperature distribution are similar, we measured the linear characteristic of flow and heat transfer for stainless steel mesh packed regenerator under low kinetic Reynolds number Reω by two pressure transducers.
