Abstract

A machine-learned (ML) subgrid-scale (SGS) modeling technique is introduced for efficient and accurate prediction of reactants and products undergoing parallel competitive reactions in a bubble column. The model relies on data generated from a simple substitute problem with a small number of features. The machine-learned model replaces the iterative approach associated with the use of analytical profiles for previous subgrid-scale models for correcting concentration profiles in boundary layers. The present model, thus, offers a significant performance bonus as well as the flexibility to extend to more complex scenarios due to its data-driven nature.

用机器学习方法模拟气泡塔反应器中甲苯的氧化反应

介绍了一种机器学习(ML)亚网格尺度(SGS)建模技术，用于高效准确地预测气泡柱中发生平行竞争反应的反应物和产物。该模型依赖于由具有少量特征的简单替换问题生成的数据。机器学习模型取代了与使用先前亚网格尺度模型的分析剖面相关的迭代方法，用于校正边界层中的浓度剖面。因此，目前的模型提供了显著的性能奖励，并且由于其数据驱动的性质，可以灵活地扩展到更复杂的场景。
