摘要:

在本文中,我们首次展示了针对空间解析、三维锂离子电池模型的局部降阶方法。我们引入了一种基于有限体积离散化分析模型的非一致局部逼近空间的局部降阶方案,并利用局部经验算子插值来近似模型的非线性项。数值示例表明了该方法的可行性。

英文摘要:

In this contribution we present first results towards localized model order reduction for spatially resolved, three-dimensional lithium-ionbattery models. We introduce a localized reduced basis scheme based on non-conforming local approximation spaces stemming from a finite volume discretizationof the analytical model and localized empirical operator interpolation for the approximation of the model's nonlinearities. Numerical examples are provided indicating the feasibility of our approach.
