摘　　要：基于计算流体动力学方法的流体体积(VOF)模型,以进入单体电池电解液的均匀性和灌注时间为目标,对双极性锌氧化银贮备电池的电解液分配箱结构进行优化。分配箱分为单进口、多进口及带多孔挡板等结构。带多孔挡板的电解液分配箱,电解液灌注时间、单体电池电解液分配的均匀度和电池内空气残余量分别为8. 5 s、7%和1%,均满足设计要求。Based on the volume of flow(VOF)model of computational fluid dynamics,the uniformity of single battery electrolyte distribution and filling time were taken as object.The electrolyte solution dispensing box structure of the bipolar silver zinc reserve battery was optimized,which included single inlet,multi-inlet and perforated baffle structure.The filling time of the electrolyte,the uniformity of single battery electrolyte distribution and the residual amount of air in the battery for the electrolyte distribution box with perforated baffle were 8.5 s ,7% and 1%,respectively,which could meet the design and operation requirements well.
