| 1 | A 100 W-class traveling-wave thermoacoustic electricity generator显示文摘Experimental investigation on a traveling-wave thermoacoustic electricity generator is presented.

| 2 | A heat-driven thermoacoustic cryocooler capable of reaching below liquid hydrogen temperature显示文摘A 'double-gas acoustic amplifier' is introduced to couple a thermoacoustic heat engine and a two-stage pulse tube cooler in this paper. Compared with previous acoustic amplifiers, this new acoustic amplifier maintains the function of amplification for pressure amplitude. In particular, the novel acoustic amplifier with a reservoir makes it possible to install an acoustic transparent but gas blocking elastic membrane between the engine and the cooler. Thus, the engine can use nitrogen as the working gas to work at low frequency; and meanwhile, the cooler can still use helium as the working gas to maintain its high performance. With this new amplifier, the cooling temperature of a two-stage pulse tube cooler driven by an energy-focused thermoacoustic engine reached 18.7 K. | HU JianYing LUO ErCang DAI Wei Zhou Yuan | 2007 | Chinese Science Bulletin2007，52，4： | 18 |
| 3 | Experimental investigation of a 500 W traveling-wave thermoacoustic electricity generator显示文摘In this paper, an experimental investigation of a traveling-wave thermoacoustic electricity generator, which consists of a traveling-wave thermoacoustic heat engine and a linear alternator driven by that engine, is presented. Using the results of previous theoretical and experimental research, we designed and fabricated a traveling-wave thermoacoustic heat engine and a linear alternator. In the experiments, 450.9 W of electrical power was obtained with a maximum thermal-to-electrical efficiency of 15.03%, and a maximum electrical power of 481.0 W was achieved with 12.65% thermal-to-electrical efficiency. | WU ZhangHua MAN Man LUO ErCang DAI Wei ZHOU Yuan | 2011 | Chinese Science Bulletin2011，56，19： | 17 |
| 4 | A novel coupling configuration for thermoacoustically-driven pulse tube coolers: Acoustic amplifier显示文摘Thermoacoustically-driven pulse tube cooler can provide cryogenic cooling power with no moving com-ponents. Up to now, pulse tube cooler is directly coupled with the thermoacoustic engine and obtainable pressure ratio for the pulse tube cooler is limited by the capability of the ther-moacoustic engine. The authors propose here the concept of acoustic amplifier, which is actually a long tube connecting the engine with the pulse tube cooler. Theoretical calculation shows that suitable length and diameter of the tube can lead to a pressure wave amplification effect which means that pressure wave amplitude coming from the thermoacoustic engine can be much amplified to drive the pulse tube cooler. Based on this, a 2.8 m long copper tube with 8 mm inner diameter is used as the acoustic amplifier in experiments. The experimental results show that due to the amplification effect, pressure wave amplitude at the inlet of the pulse tube cooler is over 2.5 times of that at the engine outlet. Typically, with 1.67 kW heating power, the pressure ratio provided by the engine is 1.11 while at the inlet of the pulse tube cooler the pressure ratio is 1.32, which leads to a lowest no-load temperature of 65.7 K. | DAI Wei LUO Ercang HU Jianying CHEN Yanyan | 2005 | Chinese Science Bulletin2005，50，18： | 14 |
| 5 | High efficiency linear compressor driven pulse tube cryocooler operating in liquid nitrogen temperature显示文摘The inertance tube is one of the key components of a pulse tube cryocooler. It has great influence not only on the efficiency of the pulse tube cryocooler, but also on the efficiency of the linear compressor. Meanwhile, it is very difficult to predict the impedance of an inertance tube because of the turbulent flow. In this paper, using a quasi-turbulent model, the inertance tube is optimized to match a linear compressor driven pulse tube cryocooler. Experimental results show that this model can predict the impedance quite well. With 127 W input electric power, the pulse tube cryocooler obtains 9.4 W cooling power at a temperature of 77 K. The relative Carnot efficiency of the whole system reaches 19.8%. | HU JianYing WANG Xiaomao DAI Wei LUO ErCang HUANG Yu | 2009 | Chinese Science Bulletin2009，54，23： | 7 |
| 6 | A high-performance ther-moacoustic refrigerator oper-ating in room-temperature range显示文摘The working principle of an efficient travelling- wave thermoacoustic refrigerator operating in room-tem- perature range has been analyzed and an experimental set-up has been built. The experiment showed that suppress- ing DC-flow streaming was very critical to efficient operation, and an elastic membrane was used to solve the problem suc- cessfully. At the most efficient operating point, the novel thermoacoustic refrigerator achieved a cooling capacity of about 80 W at ?20℃, with a much higher efficiency than previously developed standing-wave thermoacoustic refrig- erator. | LUO Ercang HUANG Yun DAI Wei ZHANG Yong WU Zhanghua | 2005 | Chinese Science Bulletin2005，50，22： | 5 |
| 7 | An acoustical pump capable of significantly increasing pressure ratio of thermoacoustic heat engines显示文摘Pressure ratio is one of the important parameters for evaluating a thermoacoustic heat en- gine. A so-called acoustical pump, which is capable of significantly increasing pressure ratio of a ther- moacoustic heat engine, is proposed. Its operating principle is given. Also, a verification experiment is done with nitrogen gas in the energy-focused ther- moacoustic heat engine, showing that the pressure ratio increased from 1.25 to 1.47. | LUO Ercang HU Jianying DAI Wei CHEN Yuanyuan | 2006 | Chinese Science Bulletin2006，51，8： | 4 |
| 8 | A looped heat-driven thermoacoustic refrigeration system with direct-coupling configuration for room temperature cooling显示文摘Heat-driven thermoacoustic refrigeration has drawn extensive concern in the past decades due to its advantages of high reliability and external heat-driven mechanism.In such a system,heat can be firstly converted into acoustic power and then the acoustical power drives a refrigerator to generate cooling effect without any moving mechanical components.So far,most of researches on heat-driven thermoacoustic refrigeration have focused on cryo- genic application,such as natural gas liquefaction [1,2].In addition, heat-driven thermoacoustic refrigeration also plays important roles in recovering waste heat and provides an environment- friendly alternative to the current abso'rption chiller especially in the small-scale power range [3-7].However,two main obstacles to use the thermoacoustic technology in practice are its relatively low cooling capacity and low cooling efficiency.Either the two-loop configuration proposed by Luo et al.[5]or the configuration of a one-unit refrigerator driven by a three-unit engine brought forward by Kees [6],they both suffer from phase-shifting tube and mismatch between the thermoacoustic engine (TAE)and thermoacoustic refrigerator (TAR). | Huizhi Wang Limin Zhang Guoyao Yu Jianying Hu Ercang Luo Ying Ma Chao Jiang Xianxian Liu | 2019 | Science Bulletin2019，64，1： | 4 |
| 9 | A 300 Hz high frequency thermoacoustically driven pulse tube cooler显示文摘This article introduces the latest progress of a 300 Hz thermoacoustically driven pulse tube cooler. Based on the experience of former experiments, improvements have been made in the standing-wave engine, pulse tube cooler and their coupling mechanism. An inlet pressure ratio of 1.248 was obtained with the mean pressure and heating power of 4.13 MPa and 1760 W, respectively. A lowest no-load temperature of 69.5 K has been reached under this condition. This is the first time for thermoacousti- cally driven pulse tube coolers to reach the temperature below 70 K with such a high frequency. | ZHU ShangLong YU GuoYao ZHANG XiaoDong DAI Wei LUO ErCang ZHOU Yuan | 2008 | Chinese Science Bulletin2008，53，8： | 3 |
