采用一体化堆叠的驻波热声发动机工作特性实验研究
Experimental study on working characteristics of standing-wave thermoacoustic engine using integrated stack
摘要
Abstract
An experimental sample of an integrated stack was fabricated using the additive manufacturing tech-nology by integrating the cold and hot heat exchangers with the parallel-plate stack,and a standing-wave ther-moacoustic engine was successfully constructed.The dynamic responses of the thermoacoustic engine at differ-ent heat inputs were analyzed.The effects of the dry and wet conditions as well as the cooling methods on the onset and steady-state working characteristics of the thermoacoustic engine were explored.The results show that as a core component,the integrated stack can generate self-excited thermoacoustic oscillations under wet and water-cooling conditions.Compared with the dry stack,the wet stack significantly promotes the heat ex-change between the working fluid and the solid stack by utilizing the phase change of water,thereby reducing the onset temperature difference.Cold-water convection cooling is better than natural air cooling in reducing the cold-end temperature of the stack,significantly increasing the amplitude of pressure oscillations and im-proving the acoustic power output of the thermoacoustic engine.关键词
