Identification of Coherent Structure Dynamics in Wall-Bounded Sprays using Proper Orthogonal Decomposition

摘要

Wall interaction of sprays emanating from Gas Centered Swirl Coaxial (GCSC) injectors were experimentally studied as a part of this ten-week project. A key aspect of the work was to apply the Proper Orthogonal Decomposition (POD) method of data analysis to time-resolved intensity images of these sprays. A high-speed camera with backlighting was used to generate the intensity movies.
