Classifying Stratified Wakes with Geoff Spedding and Chan-Ye Ohh

Join Geoff Spedding and Chan-Ye Ohh from the University of Southern California as they present their research on classifying stratified wakes in this Physical Review Journal Club session. Explore their innovative approach using dynamic mode decomposition (DMD) to characterize and automate the classification of wakes behind bluff bodies in density-stratified environments. Learn about their custom-designed algorithm that sorts wakes based on the most energetic DMD modes, and discover the potential applications of this method in analyzing more complex turbulent flows. Gain insights into the competing effects of buoyancy, momentum, and viscosity in stratified wakes, and understand how this research contributes to tracing wakes back to their sources. Engage with the presenters during a Q&A session moderated by PRFluids Editorial Board Member Keith Julien, and delve into topics such as experimental setups, numerical simulations, and regime diagrams. Enhance your understanding of fluid mechanics and data-driven analysis methods in this informative 32-minute video presentation.
