| 摘 要： | 热声发动机作为一种完全没有运动部件的能量转化和传输机械具有广阔的应用前景.为了提高热声发动机的驱动性能,本文采用变负载法对热声发动机性能的影响因素进行了实验研究.实验结果表明,负载的阻力和容抗对热声发动机的加热温度、压比和声功引出有重要影响.同时,实验中还发现了能够使热声发动机瞬时消振和起振的实验方法,将极大方便对热声发动机的开关控制.

| Abstract: | Without any moving parts, thermoacoustic engines have great potential in energy conversion and transmission. In order to improve the driving ability of a traveling wave thermoacoustic engine, factors that influence the performance of the engine are experimentally investigated by variable R-C load. Experimental results show that resistance and compliance impedance have great influence on the heating temperature, pressure ratio and acoustic power output of the engine. Moreover, method for fast stopping and restarting thermoacoustic engines is found, which makes it convenient to operate thermoacoustic engines in practical applications. |
