ABSTRACT<\/h6>\n<\/div>\n\n\n\n
\n

To follow the policy of energy development of Taiwan, this project aims to develop a thermoacoustic heat engine capable to utilize low-grade heat (below 230\\textcelsius) for practical use. The main focus is to integrate a wet regenerator and gas-liquid column oscillation in a thermoacoustic engine system. The regenerator is a key component for energy conversion. By adding water to the regenerator, the latent heat of phase change contributes to the reduction of the onset temperature of the engine. The density of a liquid column is larger than a gas column. Comparing to the thermoacoustic engine only with the gas column, adding the liquid column to the thermoacoustic engine can help to lower the volume of the engine system. For recognization of characteristics of wet regenerator and liquid column, and clarification of the integration effects, this project is divided into three years. In the first year, the wet regenerator will be tested for the realization of the basic thermoacoustic characteristics. By imposing forced oscillation to the wet regenerator, the experiments will measure the acoustic power changes and oscillation-induced heat flow rates transmitted through the wet regenerator. In the second year, the wet regenerator will be tested in a looped tube thermoacoustic engine. The hot end of the wet regenerator will be heated to exceed a critical value for inducing spontaneous oscillation. The stability curve will be experimentally obtained by adding different water mass on the regenerator. Also, by measuring acoustic states inside of the engine, the evolution of the oscillation amplitude of saturation caused by increasing input heat power will be discussed. In the third year, this project develops a looped thermoacoustic engine that uses the multiple regenerators (wet and dry) and spontaneous oscillations of liquid and gas columns, based on the result accomplished in previous years. The performance of the heat engine will be discussed under the framework the linear thermoacoustic theory.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
