Multiscale Complexities of Turbulent Reacting Flows: from Faster H2-Air Flames to Superspreading Evt

Combustion Webinar 03/16/2023, Speaker: Swetaprovo Chaudhuri
Turbulent combustion research can enable the pursuit of timeless questions, often in ostensibly different disciplines For example how turbulence flame interaction can lead to faster flame propagation at local and global levels, or what leads to superspreading events in the context of the recent pandemic? Can we make robust, mathematical models to describe them? Timely answers to these questions are pivotal to the systematic development of hydrogen based gas turbines or for the development of strategies to stop the next pandemic, respectively In this talk, we will discuss the recent advances made in understanding and modeling local propagation and structure of premixed hydrogen air flames in turbulence using Flame Particle Tracking techniques applied to Direct Numerical Simulations with detailed chemistry These developments could be used to answer questions on global propagation rates characterized by turbulent flame speed using a recently developed theoretical framework Finally, it will be shown that experience with turbulent reacting flows can be useful in mathematically describing multiscale phenomena like superspreading events the established driver of Covid 19 disease dynamics.
Prof Swetaprovo Chaudhuri is an Associate Professor at the University of Toronto Institute for Aerospace Studies, and a Visiting Faculty Fellow at the Department of Aerospace Engineering, IIT Madras He works in turbulent reacting and multiphase flows and has contributed to the understanding of turbulent flame stabilization, propagation, and structure using experiments, theory, and computations He earned his
Ph D from the University of Connecticut Subsequently, he worked at Princeton University as a research staff and then as a faculty member at the Indian Institute of Science Prof Chaudhuri has authored/co authored over hundred articles in journals, conferences, and books and has been honored by several organizations He is an elected Associate Fellow of the American Institute of Aeronautics and Astronautics and is a member of its Propellants and Combustion technical committee He also served as a member of the Covid 19 Modeling Consensus Table, an advisory body for the Government of Ontario.
