A special CCRC seminar by Professor Andrea Giusti at Imperial College London on
Date: Wednesday March 29, 2023
Location: Auditorium between bldgs. 4 & 5
Time: 14.00 - 15.00
Abstract: The use of high-fidelity simulations and low-order models for the prediction of ignition, extreme events and emissions in aviation engines and the transfer of such models to the evaluation of wildfire risks are discussed. The conditional moment closure model and its use to predict local extinctions and global blowoff of spray flames, as well as the response of turbulent flames to air flow oscillations, are first presented. Recurrence quantification analysis to forecast global blow-off in an aeroengine combustor is then introduced. This is followed by a discussion of the modelling and prediction of soot and indirect noise in a model aeronautical combustor. Low-order modelling of ignition and the use of such models in the context of wildfires is then presented. Optimisation of firefighting resources by means of methods derived from games theory closes the seminar.
Short biography: Andrea is a Lecturer in Thermofluids at Imperial College London, Department of Mechanical Engineering. He is Editor-in-Chief of the International Journal of Spray and Combustion Dynamics (SAGE publications), and Bye-Fellow of Fitzwilliam College in Cambridge. He leads a research group in multi-physics combustion and engineered fluids, where the combination of electromagnetic interactions and nanomaterials is explored as a new paradigm for the control of chemical reactions and fluid structures towards sustainability in the energy, transportation and aerospace sectors. His research focuses on the development and use of numerical methods for the investigation of a wide range of scales, from molecular dynamics and quantum mechanics to continuum. Development of models to increase resilience to climate change, for instance to evaluate wildfire risks, is also part of his research interests.
