制作出了一个平板回热器,将其置入行波热声发动机中与丝网回热器进行对比实验研究。实验结果表明,平板回热器能够有效提高行波热声发动机的输出声功,但是其热效率有所降低。
A parallel-pate regenerator was made and the experiment comparison on two kinds of regenerators (parallel-plate regenerator and screen-based regenerator) in travelling-wave thermoacoustic engine (TWTAE) was done. The results show that the parallel-plate regenerator can improve the output power of TWTAE effectively but lower the thermal efficiency slightly.
