回热器是热声系统中实现热功转换的关键部件 ,其性能的好坏直接影响着热声系统的特性。本文对回热器的长度、水力半径或板叠间隙、回热器在驻波声场中的位置等回热器特性参数对其性能的影响进行了模拟分析 ,并在此基础上对回热器或板叠特性参数进行了优化。
Regenerator is a key part in the thermoacoustic system to realize the conversion of thermal power. The performance of the regenerator has a direct impact on the characteristics of the thermoacoustic system. In this paper, the influence of the regenerator parameters such as the length of regenerator, the radius of the water or the gap of the stack and the position of the regenerator in the standing wave field is simulated and analyzed. Based on this, Or stack characteristics parameters have been optimized.
