Big data and Machine Learning (ML) are driving comprehensive economic and social transformations and are rapidly becoming a core technology for scientific computing, with numerous opportunities to advance different research areas such as Computational Fluid Dynamics (CFD).

The combination of CFD with ML has been already applied to several CFD configurations and is a promising research direction with the potential to enable the advancement of so far unsolved problems, thanks to the ability of deep models to learn in a hierarchical manner with little to no need for prior knowledge. However, this approach presents a paradigm shift to change the focus of CFD from time-consuming feature detection to in-depth examinations of relevant features, enabling deeper insight into the physics involved in complex natural processes.

The workshop is designed to highlight some of the areas of the highest potential impact, including improving turbulence and combustion closure modeling, developing reduced-order models, and designing versatile neural network architectures. Emerging ML areas that are promising for CFD, as well as some potential limitations, will be discussed. The workshop aims at gathering different research groups, by providing a venue to exchange new ideas, discuss challenges, and expose this new research field to a broader community.
