The application of ML methods to Fluid Mechanics has been growing exponentially during the last decade or less, as testified by the increasing number of review articles and the organization of Symposia and dedicated sessions in both Fluid Mechanics and ML conferences. Despite this, ML learning for fluid dynamics is still in its infancy, and the encouraging results achieved up to now, generally restricted to academic problems characterized by simple geometries and flow physics, and by the availability of abundant, complete and accurate data, is far from being satisfactory in view of the deployment of ML methods to realistic flow problems. On the other hand, fine-detail understanding, accurate modelling, and reliable prediction of complex flows remain a significant challenge for both fundamental and applied Fluid Dynamics. The development of a new generation of ML-assisted methods and models for the simulation and modelling of different kinds of flows is a key enabler toward improved predictive capabilities, with impact on the design of more efficient and environmentally friendly fluid systems.
Applications include Aerospace, Automotive and Energy conversion systems, as well as biomedical devices.
The main activities will be the exchange of AI/ML methodologies between European research and industrial groups; development and maintenance of a web platform referencing databases for the training of ML methods, test cases (for verification, validation and benchmarking of ML-assisted models),courses/workshops/conferences.
For activities concerning turbulence modelling, the SIG will work in close collaboration with the NASA Turbulence Model Benchmarking Group (https://turbmodels.larc.nasa.gov/tmbwg.html), which focuses on turbulence model development, implementation, application, and validation/verification and involves members from NASA, AIAA, and academic research institutions.
The SIG will also promote, at least once every two years, thematic workshops, and symposia.
Finally, the SIG may contribute to the dissemination of ML into the Fluid Mechanics community through the Wiki and through the organization of thematic Schools. The above events will also provide a platform in which developers of ML methodologies could profitably exchange and collaborate with researchers in Fluid Dynamics, who use or wish to use these methodologies.
The fine-detail understanding, accurate modelling, and reliable prediction of complex flows represent a significant challenge for both fundamental and applied Fluid Dynamics. The exponential growth of Machine Learning techniques, supported by the increased availability of high-fidelity flow data, is expected to play a game-changing role for the development of a new generation of ML-assisted methods and models in Fluid Dynamics. The latter are expected to ensure improved predictive capabilities at lower computational cost, with impact on the design of more efficient and environmentally friendly fluid systems.
The SIG covers all activities concerning the development and application of ML techniques to the modelling, simulation, and analysis of flows. The latter include:
Applications include Aerospace, Automotive and Energy conversion systems, as well as biomedical devices. The SIG will organize thematic workshops and schools to foster scientific activities and the training of graduate students and industry practitioners.
We look forward to sharing information on datasets, test cases, open-source software, and other relevant information.
