摘要

以斜温层厚度和效率为评价指标

开展了斜温层储热罐的实验研究

研究了储热温差、储热质量流量和径向圆盘型布水器结构对储热罐性能的影响。结果表明:斜温层形成和发展主要受到储热质量流量和布水器圆盘直径的影响

储热温差的影响较小

初始斜温层厚度随着雷诺数Re和弗劳德数Fr的增大而增大;储热过程的效率可定量反映斜温层形成及发展过程的不可逆性

总体呈现先快速升高

后保持在相对较高水平并缓慢上升的变化规律

即储热过程的耗散主要发生在斜温层形成时期;综合考虑储热时长和效率

储热过程的优化参数范围为雷诺数Re为2 372~3 320、弗劳德数Fr小于0.235。

Abstract

Thermocline thickness and exergy efficiency were taken as evaluation indicators to conduct experimental study of thermocline heat storage tank. Influence of charging temperature difference

mass flow rate and radial plate-type diffuser structure on performances of the heat storage tank was studied. Results show that the formation and development of the thermocline are mainly affected by the mass flow rate and the diameter of the diffuser

and the influence of charging temperature difference is not significant. The initial thermocline thickness increases with the increase of Reynolds number

and Froude number

. The exergy efficiency can quantitatively reflect the irreversibility of

the formation and development process of the thermocline

and it shows a law of rapid rise and then keeping a relatively high level with a slow rise. Exergy destruction of the thermocline storage tank mainly occurs during the formation process of thermocline. Considering the charging duration and the exergy efficiency

the optimization parameters of the charging process are as follows: Reynolds number is 2 372 - 3 320 and Froude number is less than 0.235.
