摘要/Abstract

摘要： 针对不同类型的锌溴液流电池通道，利用流体力学计算软件 FLUENT对流体的流动状态进行了模拟。结果表明，在相同流速条件下，直角通道和弯角通道流体的局部流速最大值都出现边壁突变处；在液流电池反应区，流体的局部流速和湍流程度的分布存在不均匀现象。通过改变进出反应区的分流通道数量和结构，可以使电解液在反应区流动均匀，改进整个流动体系的传质性能，进而使锌溴液流电池电堆的充放电性能得到提高。

Abstract:

A computational fluid dynamics program FLUENT was used to predict the fluid flow in channels of the zinc-bromine flow battery with different flow channelsThe calculation results indicated that the local velocity had the maximum values at the side wallsNon-uniform distribution of local velocity and Reynolds number were found in electrochemical reaction regionFluid distribution could be improved by changing the runner enter electrochemical reaction region which would influence the performances of mass transfer and battery
