Phenomenological flow-models for rotating machinery

Orateur : Kostas Steiros / Junior Research Fellow at Imperial College London

Abstract : Various processes of engineering interest involve complex flows, coupling turbulent dynamics, with rotation and unsteadiness. Current modelling methods require the use of supercomputers to solve for millions of variables, far too many for most practical applications. Here, I present a physics-based approach which is utilized to reduce the degrees of freedom of two flow systems (dynamic mixers, vertical axis wind turbines), and create models whose predictions show considerable agreement with data from laboratory experiments. Both models rely on the observation that an emerging feedback mechanism regulates the flow. The possibility that similar feedback mechanisms regulate other flow systems, including the turbulent cascade, is discussed.

About the speaker  : Dr. Steiros received a Diploma degree from the National Technical University of Athens, Greece. He holds a PhD in Aeronautical Engineering from Imperial College London, where he worked under the supervision of Prof. Christos Vassilicos. He was a postdoctoral researcher under the supervision of Prof. Marcus Hultmark in Princeton University. He is currently an Imperial College London Junior Research Fellow.
