项目摘要
Thermal interactions between solid walls and oscillating gas produce a rich variety of thermoacoustic phenomena such as self-sustained gas oscillations and acoustic heat pumping. The energy conversion between heat flow and work flow occurs in a stack of plates, resulting in the two classes of engines. One is the prime mover (thermoacoustic engine) and the other is the heat pump. These engines are divided into two groups called "standing wave thermoacoustic engine" and "traveling wave thermoacoustic engine". This work is to experimentally study basic properties of such thermoacoustic engines.A spontaneous gas oscillation in a resonator equipped with a differentially heated stack of plates is studied experimentally by measuring the pressure and velocity of the gas. Work done by gas parcels is observed to flow out of stack with a temperature gradient. This paper reports the first measurements of the work flow and the work source in the standing wave thermoacoustic oscillation. Results are compared with the computer simulation based on the thermoacoustic theory and provide strong support for the basic ideas of standing wave thermoacoustic engines.We have built a thermoacoustic engine consisting of a differentially heated stack of plates in a looped tube and observed spontaneous gas oscillations of the traveling wave mode running around the loop. Stability boundary and thermally produced acoustic power are compared with those for the engine tested in a resonator. The engine in a looped tube acts as a traveling wave power amplifier, whose onset temperature rations are significantly smaller than those for the engine in a resonator.
固体壁面与振荡气体之间的热相互作用产生了多种热声现象,如气体自激振荡和声学热泵。热流和功流之间的能量转换发生在一叠板中,导致两类发动机。一个是原动机(热声发动机),另一个是热泵。这些热声发动机分为驻波热声发动机和行波热声发动机。本文通过测量气体的压力和速度,对热声发动机的基本特性进行了实验研究。气体所做的功被观察到以温度梯度流出烟囱。本文报道了驻波热声振荡器中的功流和功源的首次测量。结果与计算机模拟的基础上的热声理论和驻波热声engineer.We的基本思想提供了强有力的支持,我们已经建立了一个热声发动机组成的差热堆叠板在一个环形管和观察自发气体振荡的行波模式运行周围的循环。稳定性边界和热产生的声功率进行了比较,在谐振器中测试的发动机。环形管中的发动机充当行波功率放大器,其起始温度比明显小于谐振器中的发动机。
