Structural design and performance analysis of a new type of heat accumulator
Regenerator is widely used in gas waste heat recovery and its structure determines the efficiency of waste heat recovery.Therefore,the aim of this study was to propose an improved design scheme of multi-layer plate regenerator by comparing the numerical simulation analysis,and systematically discuss its structural optimization and performance characteristics.The heat transfer process of regenerator was simulated by the method of fluid-solid-heat coupling.The different opening forms(such as through hole,double hole and double half hole),the influence on gas flow,temperature distribution and pressure distribution in regenerator were mainly analyzed.The results showed that reasonable increase of the opening could not only improve the uniformity of the internal temperature of the regenerator,but also enhance the overall thermal performance.The design of double-hole structure had prominent advantages in reducing pressure loss,improving heat storage efficiency and enhancing heat transfer capability.In addition,this paper also provided an efficient and feasible technical path for the optimal design of the new-type regenerator structure.
