  • 摘要: 球形摩擦纳米发电机因其对低频、高随机性的波浪能具有优异的捕获性能,日益受到波浪能研究者的青睐. 为了实现对其在特定波况条件下发电性能的定量研究,基于COMSOL Multiphysics多物理场仿真软件,本文作者提出了一种针对球形摩擦纳米波浪能发电机的高保真多物理场耦合建模方法. 该模型可以兼顾准确性和高效性地模拟球形摩擦纳米发电机在特定波况下的多物理场耦合作用及电能输出情况,是对当前国内外普遍采用的基于静电场的静态仿真方法的发展和改进. 基于该方法,本研究针对四电极型的球形摩擦发电机进行了建模和性能研究,实现了从推板造波到电能输出的全过程、高保真、实时、定量仿真,为对其开展结构优化设计并最终走向实用化提供了一种有效手段.

     

    Abstract: Rolling-spherical triboelectric nanogenerator (R-TENG) are increasingly favored by wave energy researchers because of their excellent work performance for low frequency, highly random wave energy. To realize the quantitative research on the performance of R-TENG under specific wave conditions, this paper proposed a high-fidelity and multi-physics coupling modeling method for R-TENG based on COMSOL Multiphysics simulation software. By using the model, the multi-physics coupling effect and power output of R-TENG under specific wave conditions can be accurately and efficiently simulated. This model can be regarded as the development and improvement of static simulation methods based on electrostatic field commonly used at home and abroad. Based on this method, this model investigated the modeling and performance of a four-electrode R-TENG, and provided the high-precision, real-time and quantitative simulation of the whole process from the wave-making to the power output. This made it possible to carry out the structural optimization design and finally to provide effective means to manufacture.
