在可再生能源需求不断增长的背景下，本研究探索了一种新型的湿气发电（Moisture Electricity Generation, MEG）技术。这项技术利用地球上最丰富的资源——水，为环境友好型能源泛在获取开辟了新途径。然而，MEG器件内部的理化过程相当复杂，难以直观分析【2】。为了克服这一挑战，本研究采用了COMSOL Multiphysics®软件进行模拟仿真，以量化阐释这些复杂的动态理化过程。 集成仿真模型结合了多孔介质流、化学反应工程和电磁模块，通过耦合Richards方程、Nernst-Planck方程和Poisson方程 ... Read More
对锂离子电池进行准确建模有利于更好的进行电池设计和电池管理。目前对电池电化学模型的建立主要是基于传统的P2D理论，将活性颗粒假设为均匀分布的球形，使用bruggman关系式近似计算固液相的有效传输参数并忽略了粒径和孔隙率在电极内的异质性分布。在小倍率充放电条件下由于锂离子浓度梯度较小，所以均质化模型可以准确表达电池的内外特性；然而在大倍率条件下，厚度方向上复杂异质性的孔隙限制了锂离子的传输，特别是对于厚电极。此时均质化模型往往低估了电池极化，导致仿真与实验结果误差大，模型不准确。为了充分考虑电极结构的异质性，本研究在传统P2D模型的理论框架下，将电极厚度方向分为多层 ...
