开发了钒氧化还原液流电池（RFB）的瞬态建模框架，并进行了涵盖钒浓度和电解液流速范围的实验。二维模型是基于质量，电荷和动量的传输和守恒的全面描述，并结合了涉及钒物种的反应的全球动力学模型。该模型对实验数据进行了验证，并用于研究浓度，电解质流速和电极孔隙率的变化的影响。扩展的模型和未来的工作提出了建议。
A transient modelling framework for a vanadium redox-flow battery (RFB) is developed and experiments covering a range of vanadium concentration and electrolyte flow rate are conducted. The two-dimensional model is based on a comprehensive description of mass, charge and momentum transport and conservation, and is combined with a global kinetic model for reactions involving vanadium species. The model is validated against the experimental data and is used to study the effects of variations in concentration, electrolyte flow rate and electrode porosity. Extensions to the model and future work are suggested.
