Title:
Optical diagnostics for turbulent pressure-velocity interactions
Research area and project description:
Turbulent flows are everywhere, from nature to engineering. Common examples include atmospheric and ocean currents, flow through turbines, and aerodynamic flows around vehicles. Despite their ubiquity, turbulence remains one of the most challenging phenomena to measure and understand, especially at high Reynolds numbers where conventional techniques fail.
The main objective of this PhD project is to advance high-fidelity experimental diagnostics for turbulent flows using cutting-edge laser-based techniques. In particular, the project will focus on developing and applying Filtered Rayleigh Scattering (FRS) for simultaneous, non-intrusive measurements of velocity and pressure fluctuations in complex flow environments. This capability represents a breakthrough in experimental fluid mechanics, enabling unprecedented insight into the coupled dynamics of pressure and velocity fields—an essential aspect of turbulence physics.
The activity is embedded in a larger research project that aims to improve data assimilation methodologies by leveraging unique, high-quality experimental data. The measurements generated by this PhD will serve as critical input for developing and validating advanced computational models, bridging the gap between experiments and simulations.
