Use of information networks for understanding hydrodynamic instability on complex wake flows
Pennsylvania State University
Abstract
Hydrodynamic instability drives the performance and operability of a number of aerospace systems, including aircraft, rotorcraft, and propulsion systems. Identifying the source of the instability and its dynamics in complex configurations is challenging, particularly in highly turbulent, three-dimensional environments. In this talk, we’ll explore the use of information network theory for identifying the critical regions of unstable flows. We apply these methods to wake flows, both single- and multi-wake systems, to explore opportunities for better insight into complex flow behaviors.
