摘要
Abstract
Study of the optimization of heat transfer coefficient and the electrolyte temperature distribution in stack plays an important role to improve the efficiency and reliability of the vanadium battery. Based on the knowledge of the convection heat transfer, a thermal model about the system of vanadium redox flow battery was proposed. After investigation of the temperature distribution of vanadium flow battery with different flow rates and heat transfer coefficient, the temperature relationship between the tank electrolyte and stack electrolyte in the system was obtained. Fluent software was used to simulate the temperature distribution of stack electrolyte under different flow rates. Results of simulation show that the heat transfer coefficient and the electrolyte flow rate are the important factors those affect the temperature distribution. In this battery configuration, the temperature distribution of stack electrolyte is uniform and the battery performance is better when the flow rate of electrolyte is 90 cm3·s–1.关键词
