采用谐波分析法,对回热器进行了模拟。针对热声发动机与线性压缩机输出压力波特性的不同,分析了输入压比对回热器性能的影响。计算了给定输入声功率、不同输入压比条件下回热器的优化尺寸,可为脉管制冷机回热器的优化设计提供参考。
The simulation with simple harmonic analysis on the performance oi a regenerator was out. Considering output pressure differences between potential driving sources, e. g. , thermoacoustic prime mover and linear compressor, the influence of pressure ratio on regenerator performance was discussed. Computation results provide optimized dimensions of regenerator for different pressure ratios at a fixed acoustic power input, which could be a preliminary guide in designing a regenerator for pulse tube refrigerators.
