Dissecting complex flows via fusion of volumetric particle tracking and data assimilation - tracking number aero, 21-048WP

This three-year, $504,413 Project Grant from the Department of the Navy's Office of Naval Research under the Basic and Applied Scientific Research program (CFDA 12.300) supports research at Florida State University to fuse experimental and computational data for the analysis of complex fluid flows. The awardee will employ a novel four-camera, four-pulse volumetric particle tracking system capable of accurate Lagrangian measurements to study turbulent boundary layers, wakes, unsteady aerodynamics, cavity oscillations, and aeroacoustics. Through data assimilation approaches incorporating governing equations and uncertain particle trajectory data in a nonlinear unscented Kalman filter, the research aims to achieve super-resolution reconstruction of complex flows with quantifiable uncertainty. Sub-awards of $150,000 each to Illinois Institute of Technology and the University of Minnesota will support developing the particle tracking/data assimilation methods in a Lagrangian framework to incorporate flow physics.
