Research progress on thermoacoustic regenerators
摘要
Abstract
As the core component of thermoacoustic devices,regenerator plays a critical role in advancing thermoacoustic technology.In this paper,we reviewed recent research progress on thermoacoustic regenerators.First,from the perspective of structural design,various regenerator configurations—including plate-stacked,wire mesh,honeycomb ceramic,and layered structures—were analyzed and compared,with detailed examination of their performance characteristics,suitable application scenarios,and existing bottlenecks.Second,studies on the acoustic field,flow field,and frequency characteristics of regenerators were summarized.Optimization strategies based on the transfer matrix method,thermoacoustic software simulation,and characteristic time analysis were introduced and evaluated in terms of their applicability and limitations.Furthermore,by examining typical thermoacoustic systems,the performance and optimization pathways of different regenerators in practical applications,including thermoacoustic engines,refrigerators,and high-frequency micro-systems,were discussed.Finally,the feasibility of applying emerging technologies such as 3D printing and acoustic metamaterials to regenerator development was explored.Promising research directions involving multidisciplinary integration,multi-objective optimization,and closer collaboration between experiments and simulations were proposed,with the aim of providing valuable insights and guidance for future studies on thermoacoustic regenerators.关键词
