The overarching goal of this research project is to develop interactive visual analysis techniques to investigate the multi-scale nature of superstructures in turbulent flows. By scale we mean spatial scales, temporal scales, and ensemble scales relating to simulation runs using different model parameters or stochastic perturbations of initial and boundary conditions. This shall be achieved by tightly intertwining high-performance computational techniques and comparative visualization techniques for multiple physical fields. We will develop combinations of geometric and physical measures to detect and analyze characteristic flow patterns and structure interfaces in turbulent flows, statistical visualization techniques to monitor the distribution of particle dispersions and the momentum exchange between high and low momentum structures, comparative visualization techniques to investigate the relationships between small- and large-scale structures in fully resolved and reduced turbulence fields, and visual analysis techniques for ensembles of turbulent flows. Our project will serve as an interface to the turbulence data that is simulated and measured in the scope of the SPP. It will be coupled to some of the research projects, to make use of real-world data sets as well as domain-specific knowledge and experience. The visualization techniques will be embedded into our open-source visualization software Flow.3D, to enable early access to our research results and validation using the data of our project partners.
