Abstract

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
