Feature-Based Analysis and Comparison of Coherent Structures in Parameter-Dependent Flows

In this projects methods are developed for extraction of coherent structures or dominant features in complex turbulent, time-dependent flows. Since flow fields are inherently noisy, robust methods are needed. A special focus is put on parameter-dependent fields. These parameters can be flow parameters such as actuation, or model parameters like the shape of the boundaries that influence the flow. New feature based methods for comparing flow fields shall also be developed. For this measures to compare the different structures are investigated. Those techniques will be integrated into a virtual lab.
