摘　　要：通过对银锌电池组各电液框内的电解液流动方式进行适当的简化,利用软件Fluent对两种流动方式(U型与Z型)中各支管内的流动情况进行了数值模拟。由计算分析可知,U型流动方式较好。为了进一步提高各支管内流量分布的均匀性,提出了改善流量分配的方案,即在进口总管中加入一分配管,并对改进后的两种类型流动情况进行了分析比较。Simplifying the flow of electrolyte in electr-hydraulic boxes of silver-zinc battery packs appropriately, numerical simulated the flow condition in multi-branch pipes of U-type and Z-type by Fluent. The calculation analysis showed that the U-type flow was better. In order to further improve the uniformity of flow distribution in each branch pipe, proposed the improvement solution-adding a distribution pipe in the inlet manifold. At last, analyzed and compared the flow of improved U-type and Z-type pipes.
