摘要:

在这项工作中,我们解决了过程工程中高效建模动态系统的挑战。我们采用降阶模型学习,特别是算子推断。这是一种从时域数据学习动态系统的非侵入式数据驱动方法。我们研究中的应用是二氧化碳甲烷化,这是Power-to-X框架内的重要反应,以展示其潜力。数值结果表明,使用算子推断构建的降阶模型能够提供降阶但准确的代理解。这代表了迈向实现快速可靠数字孪生架构的重要里程碑。

英文摘要:

In this work, we address the challenge of efficiently modeling dynamical systems in process engineering. We use reduced-order model learning, specifically operator inference. This is a non-intrusive, data-driven method for learning dynamical systems from time-domain data. The application in our study is carbon dioxide methanation, an important reaction within the Power-to-X framework, to demonstrate its potential. The numerical results show the ability of the reduced-order models constructed with operator inference to provide a reduced yet accurate surrogate solution. This represents an important milestone towards the implementation of fast and reliable digital twin architectures.
