Bridging the Turbulence Gap: Experimental and Computational Synergies for Unresolved Flow Regimes

Turbulence is one of the most complex and least understood phenomena in fluid dynamics, with major implications for energy efficiency, climate modeling, and transportation. This project aims to improve our ability to predict and control turbulent flows by combining advanced experimental diagnostics with computational modeling. Using a novel laser-based technique called Filtered Rayleigh Scattering (FRS), the project will enable combined, non-intrusive measurements of pressure and velocity in high Reynolds number flows. These measurements will be integrated into data assimilation frameworks to improve the accuracy of flow simulations. The research will establish a world-class experimental fluids laboratory at Aarhus University and generate benchmark datasets for the scientific community. The project supports the green transition by enabling more efficient energy and propulsion systems, while also training the next generation of researchers in advanced fluid science.
