摘要/Abstract

摘要： 液流框是锌溴液流电池电堆的核心部件之一,为了对已付诸应用的液流框流道设计进行评估,本文针对流道建立物理模型,以真实电解液物性参数为研究对象,借助数值模拟,进行流体仿真计算(CFD).文章详细探讨了电解液在流道内的流场分布,出口流量均匀度,流道进出口压差以及不同黏度与进口流量对压降的影响.结果表明:现有的流道设计可实现各出口流量均等,但电解液在扇形坡面设计并未能实现均匀分布,坡面结构有待优化;250 mL/min,0.018 Pa·s工况下的电解液在流道内的压降为22.3 kPa;电解液在流道内的压差与黏度的0.7次方成正比,与流量的1.3次方成正比.

Abstract: Flow frame is a core part of zinc-bromine flow battery. Flow channel model is established in order to estimate the performance of flow channel used in application. Based on numerical calculation and flow dynamic simulation on electrolyte, some issues are studied including flow distribution in channel, flow rate in 4 outlets, pressure drop and its influencing factors like viscosity and inlet flow rate. It shows that: 4 outlets have same flow rate while electrolyte is not uniformly distributed in sector area. The pressure drop in channel under 200 mL/min, 0.018 N·m is 22.3 kPa, and the pressure drop is in proportion to the viscosity to the power of 0.7 of electrolyte and the flow rate to the power of 1.3.

Key words: zinc-bromine battery, numerical calculation, flow channel, pressure drop, viscosity, flowrate
