Digital twins are becoming a key in modern design and development. We have been looking at feature extraction and development of predictive reduced-order models for reacting flow applications, where the challenge is the high-non linearity of the problem. The main outcomes are in the following open access publications:

Reactor-based models for turbulent combustion provide an effective way to handle detailed chemistry at an affordable way. We have recently been looking at the role of mixing models and chemical time scale estimation on the predictions. The results are summarised in the following open access publications:
