PREDICTIVE MAINTENANCE & DIGITAL TWIN

Machine learning for Advanced Gas Trubine Injection Systems to Enhance Combustor pERformance (MAGISTER)
Laurent GICQUEL, CERFACS

Abstract : The design phase of the next generation of gas turbine engines is a critical step for this industry and HPC facilities are already present with the use of massively parallel CFD tools devoted to the evaluation of combustors or rotating devices. Although routinely used today, these computations are usually accompanied with a number of low order models, correlations or calibration tools. This subsequent use of tools of increasing complexity is indeed necessary to capitalize on an industrial know-how, past experience… to minimize risks and dimension efficiently in an iterative manner the final and most optimal product. This workflow remains however quite limited today in terms of flexibility and sequencing. This observation is especially true in light of recent progresses in machine learning, big data treatments and algorithms as well as data assimilation techniques. If recast in the context of the so called numerical twin framework, the existing workflow can clearly open opportunities to the benefit of this industry. One objective of the MAGISTER European Innovative Training Network is to anticipate such a trend. Indeed, MAGISTER proposes to train fifteen PhD’s to this specific context whenever applied to the issue of thermos-acoustic instabilities. To do so experts in HPC, CFD, machine learning… are gathered to construct and evaluate this new framework based on emerging tools from academia as well as industry. Through the course of the presentation, the logic behind the project as well as the links between the partners will be detailed while identifying the cornerstones behind thermos-acoustic instabilities and existing solutions.
