  • This year's Lecture will be delivered by Professor Beverley J. McKeon, Theodore von Karman Professor of Aeronautics at the Graduate Aerospace Laboratories at Caltech (GALCIT). In her Lecture, Prof McKeon will utilize the tools that Lighthill honed and tools of the modern day - theoretical analysis and data-driven methods, respectively - together with novel laboratory experiments to illuminate key features of nonlinear interactions in the Navier-Stokes equations. Focusing on a spatio-temporal representation of turbulence near walls - an omnipresent phenomenon in large-scale transport and transportation - interscale interactions are identified and quantified, then reduced to key elements responsible for sustaining turbulence. Methods to obtain data-driven representations of both linear and nonlinear dynamics will be discussed, along with some implications for the modeling of wall turbulence. The work has benefited from funding by the US ONR and AFOSR over a period of years, which is gratefully acknowledged.
